"Nuna! Your blue panty with butterfly patterns is missing. I'm really sure that aunt hang it on the clothes track this morning," Dino informed.

Obsessive personalities are cool to read in fictional stories. But in realities, there are the worst people suited for horror romances. That... Includes myself.

Because I was once obsessed with my ex-boyfriend, Hoshi.

When I decided to end our relationship, I really thought I succeeded in overcoming the climax of our toxic histories. Yet my almost peaceful life turned upside down when Dino appeared.

"Are you the one who took it out?" Dino continued while we're walking home together in the middle of peaceful street.

Most observers threw quick glance on us and few pretended they didn't hear a thing. Red flushed on my cheeks as I opened my silent lips.

"Your blue panty, did you get it personally?" He asked and I was too late to cover his mouth.

"What the hell are you asking me in public?!" I shouted in a way I barely spoke.

Before our conversation gets weirder, I pulled him quickly until we reached a part of my neighborhood that has few passerby. That's when his report entered my psyche.

'My panty is missing?'

When I checked my drawer this morning, I didn't notice that one of my things are missing. But Dino, a person who's staying with me in the same roof but isn't allowed to come in my room, took note of it as if it was his.

'So stealing my pen, counting my moles and using my used towel aren't enough?! He too memorized my undergarments?!'

"Why would you worry about my undergarment!? You son of a....!"

I couldn't continue my curse because his kind mom's face resurfaced in my head. How dare I insult his gentle mother just because her son is an obsessive psycho?

"Nuna is sexy when she curse," Dino teased, soaring the tails of his lips

When we were kids, he used to be a small cute boy around the blocks. But now, the was he stands before me is like a giant hungry beast.

He bent his knees a little to match my height then whispered, "If you really love to curse, then repeat after me."

"...?"

"Nuna, says: f***k me, Dino."

My blood that was calmly flowing on my veins have ran upward into my throbbing head. I wish I could hit him with this grocery bags in my hand but of course I did not. Instead, I kicked his knee.

"Oopps," he uttered after he successfully avoided my attack. Walking backward, Dino winked at me while licking the corner of his lips. Then he flee and ran first towards aunt's house where we're both staying at.

This guy is indeed crazy and dangerous, but so far, he didn't do anything to me. Except of those surprising skin ship or annoying stalking both in my things and in my schedule.

I hate Dino, as he reminded of my past self; the old me who's afraid to take the same path of my crazy mother. However, he's better than the creepy person behind the mysterious text messages I received weeks ago.

"Hey! Wait for me!" I shouted, trembling to be left alone so I followed his tail.

It's been three weeks since I received three messages from an unknown number.

The first text goes like this:

[I guess, I'm the obsess one because I still think about you, (Y/n)]

The second was:

[It's going to rain. Take care]

And the last message was:

[Who is that guy? You haven't date anyone before so who is that guy with you?!]

At first, I thought it was from my ex-boyfriend, who just annulled his engagement with his recent relationship. But a part of me concluded he might not be. And in fear of having someone watching creepily behind my back without my consent, I went to the police and asked for help.

Aunt and Dino don't know anything about this. I mean... I choose not to worry them when it wasn't confirmed yet. Though I did talk about my concern to one of my colleague in work, Yerih.

"So it's really missing," I murmured while looking at my cabinet.

Hoping that Dino's report is just a bluff, I searched for my blue panty that I used the other day and washed together with my other laundry yesterday. Aunt picked my dried clothes in from the clothes track so I asked her if ever she saw my missing panty but...

"Blue panty? Oh? I couldn't remember. But if it has butterfly patterns, then maybe I didn't see it. Cause it'll definitely occur in my mind since I hate butterflies. I'm allergic to it," Aunt replied.

Alone in my room, I hugged myself. My toes were curling while cold sweats built on my palms.

'Was it related to the stalker I reported to the authority?'

'Is this his way of saying that I shouldn't make a move against him?'

'Knock knock!'

My breathing stopped for a moment when I turned my head onto the door.

"Nuna, it's me, Dino."

When I heard his voice, I exhaled. Since when did I feel grateful that I have him on my side? At the moment he fetched me outside our company during that rainy night?

No matter how thankful I am, I shouldn't forget that he is also in the list of person I must avoid.

"What? I told you that you aren't allowed to come inside my room," I threatened as soon as I opened the door.

Dino pulled his lips upward just on the left side. He rolled his eyes, chuckled slightly with a little shaking of his head. Just what I thought, this guy doesn't know what a real sweet smile is.

Every time he raise his mouth, it was always a smirk.

"I really don't have any intention of going in. But now that you said it, I was tempted."

"Dare to. I'll kill you."

"Ohh, I love that. If I'll die in Nuna's hands, I'll be happy."

Crazy. I didn't bother emphasizing that word that was repeatedly came in my mouth whenever he's around.

"What do you want?" I asked.

"You only had one bowl of oatmeal and half of an apple."

He spied on my meal again?!

"So I guess you don't have any appetite at all. Is something bothering you?"

If there's one, it includes Dino. But our conversation will become longer if I answered that so I tactically changed the topic.

"I'm on a diet."

"Diet? Your waist line is 25 and you weighed 45kg. And diet? That's too much!"

Okay. I'm tired of this. I just wanna f*cking get rid of him out of my sight!

"Dino," I sighed. "Will you please get o..."

"So I'll brought you this."

A box of milk appeared. I traced the milk before looking back at his face.

"You won't say it but I guess you are troubled by the thing I said this morning. So to help you have a goodnight sleep, drink this."

He's creepy. Yes he is. However, I kept on wishing that he has room for improvement- a moment when he'll realize how to love someone without obsession. And if ever he can do it, then I'll believe I can forgive myself for my selfish treatments towards my ex-boyfriend in the past.

"Are you sure you didn't put anything in the milk?" I suspected after getting the milk.

"How could I put something inside a sealed box?" He laughed.

"Well, there's a new invention nowadays when you can inject chemicals in sealed products."

"Your imagination is really wild, nuna."

"Thank you for this. Go back to your room and goodnight."

I closed the door but he placed his feet between the closing entrance. So I opened it again.

"What?"

"About the missing panty incident," he uttered in serious tone. "Don't worry about it. I will make sure it won't happen again."

An eerie grin slipped from his lips, giving me goosebumps from toe up to my scalp.

"I will protect your panty and..."

I shut the door without hearing the rest of his oath. That freak, geez.

Morning has broken.

I went early to my work since it was easy to grab taxi in the early morning. Train and bus aren't my taste since I hate associating with tons of people. So even if it's expensive to take taxi everyday, it's my pleasure to take the risk.

"What happened to your stalker? Did the police find a clue?" Yerih, my coworker asked.

"Not yet," I sighed on my seat. "They said that he used burner phone so they couldn't track him."

My friend sighed along with me, making a long face as if she is me. Somehow, her worries have lightened my burden.

"Thank you, Yerih."

"Huh? About what?"

"For worrying about me."

"Ehh? No! Don't say that." She pouted her lips. "I feel so sorry for not doing anything to help you catch that bastard."

"But you kept on sticking by my side at work."

"That's it. I can't follow you on the way home. So I feel apologetic."

"Geez, you're cute."

"I know." She tucked her hair behind her ears. "Speaking of cute, that little boy will come pick you up after work again, right? What is his name again?"

"Dino?"

"Right! Dino. He's a college student in which university?"

"Seoul."

"Woah. That means he's pretty smart. Help me hook him up to my little sister."

"Dino? To your sister?" A crackle of laughed soared in my throat. "No way. You should choose another candidate."

"Why not? He's cute and smart. He will definitely suit my sister's taste."

"If you don't want any trouble, better not choose a guy like him."

I won't tell her that Dino has an obsessive personality once he made his mind but I can avoid giving disaster to another people.

"Don't tell me, he's your guy?" Yerih added.

"Pardon?!" I gasped, mouth opened.

"He always pick you up every night. Also, you're living with him under the same roof. Even if he's younger than you, it is not impossible you'll grow feelings towards that good looking puppy."

"I don't! I won't! Never ever!" I scolded.

"If you're worried to get criticism by dating a younger guy, don't bother. It's a trend nowadays."

"No, really. We're not in that kind of relationship."

"So why are you so against of introducing him to my sister?"

It's not because I'm jealous. I just feel bad to whoever he will date in the future. Unless a woman that can change him will appear, then she's a saintess.

"Omg! Look at this guys," one of our coworkers, Eugene, came closer with us with his phone. Others also came to my table as if it was designed to be their gossip place.

"Hyinge? Isn't that your neighborhood?" Yerih asked me after she saw what Eugene has on his phone.

Curious, I also take a look.

[The panty thief was found dead on the alleyway on Hyinge street this morning]

I couldn't react anything other than my roundly opened eyes.

"He was found lying on the ground with the panties he stole. That's very disgusting," other laughed.

They soon scattered, away from my desk and went back on their seats as if the show just ended.

'Someone's dead? In my neighborhood? Isn't the killer scarier than the panty thief?'

"You should be careful on your way home, oh my gosh." Yerih patted my back before she also walked away and went back on her desk.

Pretending I'm okay, my trembling hands caressed my chest.

'Don't worry. It's just a crime happened among million disasters in the world. Nothing will happen if I'm careful.'

I inhaled-exhaled sharply once more. Then I opened my cabinet to get some gum.

Blue butterfly patterned panty.

It wasn't the gum that my hand touched but a soft undergarment inside my cabinet. Yesterday, this piece was missing in my closet. But now it suddenly appeared, more surprisingly, in my workplace.

I quickly closed the cabinet with a bam.

'Bam!'

Eyes pierced in my place. I couldn't meet everyone's gaze but I'm sure they're are curios on my weird behaviors.

Some words echoed, asking me if I'm okay but it wasn't clear for me to reply them. Everything colors around faded but that cabinet's image grew stronger. It is the only thing I can identify.

I gulped hardly.

I bit my lower lip in order to stop it from shaking too much, until I could taste a fishy savour on my tongue.

Once again, I bravely opened the cabinet. And yes, my eyes weren't wrong. Inside has my missing undergarment that's very impossible to appear here.

A small note is on the side. Thick sweats ran down on my forehead as I picked it up and read silently.

[How dare he snatched my girl's undergarment. Don't worry my love, I took care of it.]

"Oh sh*t," Yerih's voice woke me up. That's I realized that my other colleagues are standing around me. They all have the same expression, but it won't surpass the horror in my face right now.

If the perpetrator of the mysterious messages and the one who put this here, then that means...

"He is inside this building," I whispered.

"Attention, everybody!" Our team leader came inside the office and gathered our attention by clapping his hands. "I will introduce you our new manager starting today."

A person came in behind him. He has slanted small eyes, thin lips and pale skin. It's been years, but there's no way I'll forget his face.

"This is our new manager, Kwon Hoshi."

"Hello everyone, nice to meet you all," my ex-boyfriend greeted.
