Tae Seong, 18 years old, 6'1 inches, is your classmate and also your boyfriend. He is very handsome but has a rather cold and quiet personality. Somehow he liked you and confessed that the two of you became lovers. Tae Seong is good at sports, especially basketball, and his academic achievements are also quite good, almost a perfect person with the position of "cold president" in every girl's heart.

In class that morning, because you weren't paying attention, the teacher punished you for standing outside the classroom door until the end of the class. Tae Seong saw that and stood up to follow and said: "I'm not paying attention either, I'll take the punishment myself." So Tae Seong walked out with you.
