I haven’t been reading consistently, but what I have read, Won is the most inoffensive. Seonho is the type of character that doesn’t say what’s on his mind, so the first time they had sex, he didn’t raise any objections, even when he could/should have. Won is an unsocialized man-child, and he has this sort of childish devotion towards Seonho, so even though he’s done bad, it was never done because he wanted to hurt Seonho. I think that’s the difference between him and all the other guys who’ve wronged Seonho. I’m not justifying him, but he’s definitely not the worst.

How can people call WON a BLACK FLAG when he never was...
People forgot a very important line in this manhwa in between all those r@pes...
WON BEGGED AND PLEADED EVERY ROTTEN AROUND HIM to spare seonho, to let seonho live, to be away from seonho so that no rotten can lay a hand on seonho since the very start.
He was pitiful.
They pitied him and kept a distance from seonho.
They pitied how his only LOVE maybe taken away from him if they bit him.
They pitied him seeing how he struggled to live in this hellish world since the birth as he never belonged to neither humans nor rotten.
They pitied him seeing how desperately he searched for the LOVE his mother talked about. ROTTEN PITIED WON.
Isn't that why rotten never approached seonho and humans had their way with seonho. If rotten are anywhere near seonho, they wouldn't have laid their dirty hands on him. It's not like HUMANS LISTEN just cause they are asked, or pleaded. They never listen. That's why all these r@pes happened.
They know seonho had become WON's only weakness and gotten passed around to be r@ped by one hand guy, red haired guy, a full gang, seonho's best friend, the window guy too...
won tried to save him from one r@pe just to throw him at another (unknowingly)... the cycle kept repeating till seonho got a womb inside him and even after that...
HOW CAN BOTH WON AND SEONHO BE PITIFUL . They need a break and happy ending. Please .
I can't tolerate if anyone ever said anything bad about WON and seonho... NEVER...
WON will always be my baby and I love him so much. I can't tolerate a thing about my baby
