Wait what contract? Did I miss something?

I think he signed a contract with the light brown haired girl to not make any moves on siwon because they both like him and they all have exams.. I’m not too sure though :P

Ohhh u mean that gray haired girl from the student council. I remember now. Ahhh why does he have to sign it. Like obviously siwon( if that's how I remember correctly is mc name)doesn't have any interest in her

She’s persistent nonetheless lmaoo
