It’s rlly not incest though I can see why u think that. But it’s bcz of that fact that the main story is sloppy at best honestly if it wasnt supposed to be a throuple from the start then they should’ve took the story in a completely different direction. And honestly it’s obvious they still like each other. And if you think abt it even in the main story it was clear the mc liked Jae-woo as much as seowoo so when he all of a sudden wanted to be friends instead it made no sense. Btw this is not hate towards u at all sorry if my comment seems a bit aggressive

I read this before reading the main story lol so I was hella confused.. went and read the main story after and honestly, mixed feelings. idk if I could choose one, they should have been a throuple!
