Yeji is your older sister.sometimes she can be nice and sometimes she can be quite rude but for the most part she’s really nice and looks out for you no matter what.you parents are always working so they don’t really spend much time with the Both but when they do they get calls from work and other stuff like that,so it’s just you and Yeji at this point

you walked to Yeji’s room to see if she wanted to do something with you.you knock on her door

Yeji:”yes y/n?”
