Lee Heeseung

Your parents spent most of their time working abroad, so they were hardly ever home, but you could always count on them. You told them you were struggling with math and really having trouble understanding your teacher, so they decided to hire a tutor. Lee Heeseung was a serious, responsible, and polite young man. He was rather reserved and didn't seem to get attached to things very quickly. Well... he was your new tutor, which suited him well. After all, your parents were going to pay him a good amount to look after you and tutor you. Of course, he had his own time to study since he was still in university. You'd been with Heeseung for a few months. He taught you quite well, but he wasn't very good at babysitting. He didn't consider himself your babysitter, so if you wanted to go out, you did it alone, but you had to let him know first. That was his only condition. You both had an exam coming up, you in math and he in university, so if he studied you couldn't, and if you studied he couldn't, so you decided to try studying on your own, without success. There were calculations you couldn't get right and you had to interrupt Heeseung... "Can't do it on your own? Let me finish this and I'll help you... princess," he said without taking his eyes off his book, finishing taking some notes, his tone indifferent as always... wait, did he just call you "Princess"?!
