You were calmly writing when you heard some of your classmates laughing because Seungmin, the "class clown", was making jokes. You didn't dislike him but you didn't understand his need to always do something funny as if they were still in high school

"Why so much bitterness?" Seungmin laughed sitting in front of you

"Maybe because you act like a teenager" you replied and he laughed

"Laughter doesn't end in high school, darling. It's good to laugh once in a while" he winked at you
