The next day after sending Yerin to the college with her car, SinB headed straight to the convenience store infront of the college. SinB didn't have any classes that morning so she thought she will use this chance to do some investigation.

The store's for rang, and SinB rushed towards the counter where she confronted a man in his early 30's, looking at her in confusion.

"Can I help you miss?", he asked.

"May I take a look at your CCTV record yesterday?", SinB asked.

"Is there something wrong? I can't let you unless it's something important", he answered.

"Yes it is. My wife was sexual harassed yesterday, here. I wish I could take a look at the predator for a while...", SinB explained.

Later after SinB's discussions and talks with the store manager and owner, finally SinB was allowed to see the cctv record from yesterday.

She tried to look every inches of Yerin's movements, starting from where she entered the store,  buying some food and drinks, and eating it alone at the dining corner. SinB could just smiling while looking at how Yerin enjoying her food deliciously.

"Gwiyeowo~"

But then, someone interrupted Yerin and SinB couldn't help but to clenching her fist tight as her heart was burning in anger. She knew that man. That one annoying scumbag man who ruined SinB's beautiful face weeks ago.

"It's you huh?"

Yerin was just came out from her class, together with Sowon as usual. But then someone already there, waiting for her infront of the class door.

"SinB?", Sowon asked as she qas shocked that a 'famous' person like SinB was there, standing right infront of them, looking at Yerin. Yerin was startled to see SinB meeting her like this, in public.

"What are you doing here?", Sowon asked in confusion but still, SinB didn't answer her.

"Follow me...", SinB suddenly grabbed one of Yerin's hand to bring her somewhere more quiet with no people around. Sowon just looking at them, still confused with the situation.

"Well... I know Yerin used to live with SinB when they are kids. So I guess... that's normal?", Sowon lifted her shoulder, trying to ignore what just happened and then walk away to only hod knows where.

"Why did you want to meet me?", Yerin asked after she and SinB finally arrived at a safe place where they can talk about their secret comfortably.

"I saw him at the convenience store...", SinB said.

"What did you mean?", Yerin asked.

"I saw him thru the CCTV, and I know him", SinB answered.

"You know him? You knew Choi Sungjoon?", Yerin asked.

"Next time when you saw him again, get away from him as soon as you can", SinB starred deep into Yerin's eyes. Yerin can saw the worried expression thru SinB's orbs. Yerin then nodding her head.

"A-Arasseo...", Yerin answered with her low tone.

"But you said you knew him?"

"It's none of your business. Just get away from him when you saw him nearby. He's a dangerous person, trust me", SinB held one of Yerin's hand, holding it tightly, trying to make sure that Yerin follow all her order, for Yerin's safety.

"You always said it's none of my business. Well, I'm your wife! You should tell me", Yerin make her face closer to SinB's, looking straight to her eyes. She just want to say that she was serious with her words. SinB need to tell her instead of keeping it a secret to herself.

"Later...", SinB let go off Yerin's hand, lowering her eyes looking to the ground. She don't want to tell Yerin what actually happened between her and Sungjoon.

"Then... I'll get going...", then SinB walk away from Yerin silently. Yerin just looking at SinB back view who slowly disappeared from her sight. Then, Yerin let out a heavy sigh.

"Gosh... Hwang SinB... Sometimes you acted so nice but also sometimes you were so stubborn and ignorant..."

...................................

It's 7 in the night, SinB was alone at home, secretly drinking a bottle of soju to relieve the burden she tried to endure alone.

Sungjoon had criminal records.

Few hours ago, SinB go to the police station, trying to submit the cctv evidence she has, trying to punish Sungjoon with law after what he had done to Yerin. Later she was informed that Sungjoon wasn't that much 'clean' person.

"This student has lots of criminal records before", the police said to SinB.

"Ne?" - SinB

"Molesting girls, peeking, stalking, use of substances... and bullies", the police said after scrollimg everything he had about Sungjoon on his laptop.

SinB was shocked. She really shocked, and scared at the same time. If Sungjoon was this 'crazy', SinB know that she need to protect Yerin at all cost. She didn't want Yerin to become one of his victims.

"T-Then... what should I do sir? I'm worried about my wife", SinB said to the policeman.

"I suggest you can asked the police for help. We can guard her while she was outside. Actually asking for police help was a bit difficult process, but since this Choi Sungjoon had lots of records in our system, we was sure enough that he was a dangerous predator"

Yerin came home an hour later. But why she was back at the Hwang's mansion? SinB asked Yerin to stay her for few days more. Yerin don't know the reason why but she gladly following the request.

When Yerin arrived home, she was startled when she saw two police officer was right infront of the house gate in pursuit. Yerin questioning herself, did something bad just happened?

"Your identity miss?", one of the police asked.

"I'm Jung Yerin. The---"

"You may go inside", the police officer answered, and Yerin lifted one of her eyebrows in confusion. She was so confuse right now. Why is there police infront of the house?

Didn't want to waste much time, Yerin rushed towards the front door, worried about SinB. As soon as Yerin opened the door, she was shocked when she saw that SinB was there, at the dining table, sleeping(?) probably.

Yerin walking straight to the dining table, shaking SinB's body to wake her up. Then she saw a bottle of soju not far away from her body. That's when Yerin know that SinB was drunk.

"SinB-yah... wake up. What just happened---"

"Oh? It'S yEriN eOnniiiii~~", Yerin was startled when SinB suddenly cupped both Yerin's cheek with her hands. Yerin eyes was widen and her cheek was redden in embarrassment.

"Ah sh*t... I NeEd to ThrOw aWaaay thiS boTtle! YeriN eOnNi wiLL beee MaD at mE laTeRrr~~", SinB suddenly stand up, grabbing the bottle and throw it inside the trash can. Then she came back to the dining room with her silly drunk smile.

"I did'Nt driNk AnyThinG~~~", SinB said to Yerin, smiling brightly in her drunk condition. Yerin laughing a lil bit, looking at how silly SinB was right now.

"Alright alright~ I know you didn't drink anything", Yerin smiled back and holding SinB inside her embrace. It's been a long time since she last saw SinB smiling that wide. Then, Yerin slowly bringing SinB to the sofa at the living room, trying to make her sit.

"By the way SinB-yah, why is there policeman outside---"

"ThaT ScuMbAg Choi SungJoON!! He waS a cRimInALLL!! I neEd tO proTecT yoU fROm that buCkeTheAd!!!"
