I was thinking the same BUT -- She's not actually regular. We've been so brainwashed by Manhwa to think that she has an ordinary appearance. She's actually gorgeous, confident, and has a successful career.
Bro, dudes in real life just find other chicks and get on with their lives. Guys are rarely this complicated and are usually egomaniacs who don't want to show their emotions and try to rationalize them. It was already enough that one dude was obsessing over her for years, but three of them? That's so fucking unrealistic. And I know it's just a manhwa, but still, I liked it’s potential and art, and the fact that she is a normal woman with a normal-looking body and is actually accomplished. Sighs.
Fr tho why are they all so obsessed with her? Like what are the odds that a bunch of super hot 3 guys are obsessed with a regular lady for no reason? It's the romance gods at work again cuz this stuff doesn't happen irl
