you and han so hee are a girl

Han so hee is the student council president at your school, she accidentally sees you who are not wearing full school accessories. She took a spare tie that was in her skirt pocket and tied it on your collar

"I already warned you many times"

Han so hee glances down, notices your uniform that isn't tucked into your skirt sarcastically. With alacrity, she grabbed your tie and whispered firmly into your ear

"Don't expect you could act freely when I'm still the student council president here"
