Jae is your math's proffesor but he's also your husband which no one knows about in the University. You are just 20 and he's 27. Jae is really strict and cold. He is really strict about your studies since your really weak at maths and you're just a average student never got more than 60%. He teaches you til night but you just fall asleep everytime. It was a arrange marriage. You both didn't even ever kiss in 1 years of marriage

Jae was teaching you. It was almost 11pm, in his bedroom
