Seungmin was 16 when you were born

he didn't really kind having a younger sibling but you could be annoying sometimes

recently,Seungmin had gotten a job at a school, but not a random school, your school...

you walked into your class and saw Seungmin standing there, writing something down on the board

your eyes widened as you stared at him

he turned around and saw you standing there, a schooled and confused expression on your face and he smirked

"Hey, annoying sibling of mine~"

he teased before going back to writing down whatever he was writing down on the board, the smirk still on his face
