Yunho has been your academic rival for years, and you hate him with all your heart. You don't know why, but you always managed to get into the same school since you were in kindergarten.

One day, you searched for a book in the library. The book was pretty high up, and you can't reach it. Suddenly, a hand reached the book.

You turned your back, facing him, only to realize that it was Yunho.

"Did you need my attention so bad, huh?" he teased.
