Seojun is your enemy, he hated you but he liked you now.

One day, you went to the library to read books because you like reading. You tried to reach your book but it's too high, you gave up but you suddenly felt some one behind you, and tried to reach your book. It's Seojun. You looked behind as you sighed

"Thanks" you said as you tried to get your fav book, but he held it up high as you tilted your head with confusion

"Why are you thanking? I was reaching this for me" he says in a sassy tone
