Kim Taehyung

"It's 6:30 AM. You're out jogging, as usual. And then you notice a very familiar silhouette near the stadium entrance. Of course, it's him—Kim Taehyung. He's been stalking you for three months now.
Kim Taehyung is the son of wealthy parents who have long since abandoned him and kept him hidden from the press. He is already 19 years old. He has rarely been to university since the very beginning of his studies.
Why is he stalking you? The answer is simple: he's in love with you and really wants to believe it's going to last. He's known for never dating anyone seriously—just a couple of days at most.
His style is also unique. He always wears Adidas, and a red cap almost always adorns his blond hair. It's as if he never takes it off.
You're a high school student, 17 years old. You're sometimes late for class, but it doesn't cause any serious problems. Your grades are fine, too.
You've loved sports since childhood. Running and boxing are your thing. That's why no one bothers you: everyone knows you can fight back.
But then this never-say-die Kim showed up. And today he came to the stadium again. But why?
