My mother and their father went to Hawaii after the wedding day. They left the three of us; Mingyu, Wonwoo and I.  Great. I am alone with my two step brothers. What an unlucky bitch!

"Sis, I made dinner for us!" Mingyu shouted outside my room but I didn't answer. I put my earphones instead and play 'Rachmaninov- Piano Concerto No.2', a classical music my late father used to listen.

My eyes wandered outside the window. Tonight, the moon is playing peek-a-boo, weaving in and out of ribbons of black clouds scudding across the sky. "Soon, there will be downpour of rain," I muttered, hands placed under my chin.

Lightning cut crazy zig-zags into the black sky, and it followed by a thunder that seems top almost split the heaven apart. Someone pulled my earphones and he made me gave all of my attentions to him.

"What?" I asked in irritated tone.

"I said let's eat. I said it for almost a hundred times," Mingyu said.

"Did you count it to a hundred? Liar. 2 minutes is not enough for you to say 'Let's eat' a hundred times. Stop exaggerating BROTHER."

One of his brows raised, maybe I irritate him.  "My sister is such a brat," he sighed.

"Then let's not bother each other business," I marked and about to put my earphones back. But Mingyu grabbed my wrist and left me no choice but to get dragged on the way to the kitchen. His grip was strong though.

Wonwoo is already sitting in front of the foods. When Mingyu and I stopped in his front, he looked at our clasped hands. Mingyu quickly pulled his hand back and starts to explain, "I a-am just forcing her to come out from her room a-and join us for dinner."

"No big deal. She is our sister. What's wrong in holding hands?" Wonwoo said before he stares away.

This is awkward. The reason why I don't wanna join them is because,  things between us are unusual. When I almost realize that I love Wonwoo, Mingyu unexpectedly confessed, then our parents got married and now what?! Two brothers and their step sister are alone under one roof!

I sat across from Wonwoo and beside Mingyu's seat. All I need is to eat. The faster the better so I can go back inside my room. I dug into the foods without words, and without looking at them.

"I wonder when will our parents come back? I hope their honeymoon won't be that long," Mingyu said.

"Isn't it favor for you Mingyu?"  Wonwoo's respond. "Since our parents are not here, you can have (y/n) by yourself." Wait. This guy... This bastard!

"W-What are you saying big bro?" Mingyu chuckles as his face turned red. "You made it sound like I have something with (y/n)."

"That is the truth though. You like her. Mingyu you like (y/n), as a woman."

I glared at Wonwoo to shut his mouth but he never knows how to stop!

"You said you have a crush on her that's why you were against our parent's wedding. I heard all of it when you confessed outside her room."

Mingyu couldn't look at me. He is just staring his brother like he saw a ghost. "How d-did you hear it?" he stuttered.

"Actually I was inside her room that time. And we were about to kiss before you came and interrupted the scene."

Mingyu's face turned from red to a pale white. He bowed his head down and I saw how he clenched his fists, maybe because of embarrassment.

I need to do something, even though I, myself, want to disappear right now.

"There is no point in reminiscing the past. Because we became siblings, we should forget everything that happened. Am I right, BROTHER?" I said to Wonwoo as I smile, a smile while gritting my teeth.

"Oh no sister, it will be hard," Wonwoo replied. "Look, it is raining outside. How can I forget our kiss under that rain that night? It was my first kiss so maybe, I won't forget your lips, your eyes, your breath, every inch of you."

Idiot. How can you say that after letting our parents get married? Why are you confusing me with words again?

"I can forget it," I answered. "Since it was not my first kiss."

The two gawk their eyes on me. Yes, with those seven words, I got their inner attentions.

"W-Who is your first kiss then?" Wonwoo asked.

Maybe I am desperate to end this craziness. "Your friend, Seungcheol. He is my first kiss."

Another loud thunder roared up in the heaven.

"S-Seungcheol!" Mingyu exclaimed.

"What are you doing? You are pulling another guy inside your harem. Aren't you a bitch?" Wonwoo stated, not breaking his glare on me.

A  bitch? Well, maybe I am.

"But sorry sis, I won't buy it. You and Seungcheol are impossible," Wonwoo grins as he shook his head.

"T-That's right. It is impossible for Seungcheol to like you, (y/n). I knew him more than anyone," Mingyu added.

"Then what about a bet?" I offered.

Wonwoo froze before meeting my gaze.

"Let's bet if I can make Seungcheol mine. What do you think? An 80 dollars worth of a bet, just like the old time. Deal?"
