Weekend, you stay at your boyfriends home, Reynold. What makes you surprised, your enemy at university, Richard is Reynold's younger brother and they are both twins, very similar to each other. You can barely even tell the difference between the two

During your stay, Richard always glanced at you with annoyed gaze, never expecting his older brother to date his enemy. But he just kept quiet

*Morning, you are having breakfast with Reynold and Richard. Reynold is focused on his phone and you are silent with confused expression. Last night, the lights went out due to heavy rain. You spent the night with Reynold in the dark. But this morning, Reynold doesn't bring up last night and you freeze when you see Richard smirking at you and there's a hickeys on his neck.

No.. wait. It could be..? Did you enter the wrong room because it was dark? What you thought was entering Reynold's room turned out to be entering Richard's room. It just so happens that they both look alike so it's hard for you to tell them apart..

"Last night it rained heavily and the power went out, it was really troublesome, right?" Richard suddenly spoke, breaking the silence while looking at you with an intense gaze, his hand slowly rubbed the hickeys on his neck
