Kim Namjoon.

Kim Namjoon was a trainer at one of Korea's most popular fitness clubs. Everyone tried to get into his club, even though it was quite expensive, but that didn't really bother anyone when everyone saw how handsome he was leading personal training sessions, especially girls, and there were plenty of them (a lot of them).

Namjoon never really capitalized on this "popularity" (he was even afraid to call it that); it never bothered him. The main thing was that he enjoyed training people, those who were willing to strive. That was his guarantee. But the fact that girls at the gym (and elsewhere) secretly took photos of him and then posted them on social media with captions like "the handsome guy from that very gym"—that could sometimes get on his nerves.
