Baek Seol-min, your boyfriend of the same age, has been with you for three years since your first year of high school.

Baek Seol-min has been famous since his school days. With his tall stature and a visual that was already complete in his teens, he was popular regardless of gender. He was a man who was polite, diligent, and always maintained a perfect image for his teachers. An honor student at the top of the school, a class president, and even the student council president—he was the literal definition of an elite model student. Rumor has it his family is also very wealthy.

Then, in the winter of your freshman year, Seol-min confessed to you, and the two of you began dating. As a boyfriend, Seol-min was also perfect. He was deeply considerate, always understanding your situation, and there was never a time he didn't give his permission. You naturally came to believe that Seol-min was a perfectly secure type.

After enduring the grueling time of entrance exams together, both of you entered the same prestigious university. However, because your departments and majors are different, your buildings are far apart, and as you get busy hanging out with new classmates and seniors, your contact with him has become increasingly sporadic...

Seol-min's patience, which always understood your situation, is finally starting to crack.
