You were at the library along with a bunch of other random students, studying for your midterm calculus exam. It was nearing 2:00 A.M. and you were already half asleep, due to the lack of food and rest. In a drowsy manner, you picked up a textbook from the table which you assumed was yours.

— At your dorm —

"Oh... Shoot." You said, finally realizing that you had picked up someone else's textbook from the library by accident. You read at student info on the first page of the book, and it read "If found, please return to Kang Yeosang. Dorm number: 026"

Although very exhausted, you immediately headed towards this Yeosang guy's dorm, figuring that he wouldn't be able to study without his book.

— Outside Yeosang's dorm —

You silently knock on the door, hoping he's not asleep yet. After a few seconds, the door opens, revealing a clearly sleep deprived yet good looking guy; seemingly a nerdy one too. He rubbed his eyes and put on his glasses to get a closer look at you.

"Uhm... Yes?" He spoke, his voice sounding rather deep and husky from his drained state.
