I gave it a shot, but I'm not a fan of this one.
I found the villains TOO annoying (uncle, cousin, asshole ML), and at first I couldn't figure out why---after all, villains are supposed to be un-likeable, duh. But they're just TOO stupid.
The ML is contradictory (sees her for the first time in many years, "Oh, I can't stand this girl"-->goes out of his way see her again). So is the uncle (supposedly he proposed to the aunt and loves her-->acts like a total dick to the aunt).
Also, every villain hates the FL pretty much immediately, and their reasons are either completely unexplained or paper-thin at best. A good villain still has some sense of reason about them, however flawed; but this is just dumb. If they had fleshed out those characters a bit more, I think it could've been a better read.

I really tried to like this, because the art style is so good, but it's SOOOO FUCKING BORINGGGGGG!
It's possible to make a character whose main trait is "I'm sad and fearful of everything" actually work, but this story can't. The protagonist has no personality and is completely one-dimensional. In fact, it seems like all the characters I've seen so far (dad, father) are just as bland.
Also, the story is way too fast-paced.
Fellas, is it weird that I'm still on Mok-yeon's side here....?
(Yeah, the rape fantasy is fucked, but he didn't do it irl. And I'd say most people have intrusive thoughts/fantasies about hurting someone they dislike and stuff. I think that's basically what was happening there; except, it was moreso a fantasy about "lashing out" instead of actually "hurting" Nanjo.)
I've seen enough evidence to conclude that Mok-yeon doesn't ACTUALLY want to harm Nanjo. His sexual preferences in the past have been rough, and he 1000% coerced Nanjo into this physical relationship, yes. But he never really desired to physically HURT him.
I honestly feel really terrible for Mok-yeon. Sure, he's been a cheater in the past, and that's shitty. BUT NANJO NEVER KNEW THAT ABOUT HIM. Nanjo just saw a promiscuous dude with tattoos and a BDSM preference, and assumed he was absolute scum [abusing a twink] from the very beginning, without even knowing him.
Mok-yeon was helpless from the very start; he felt he had no choice but act according to the stereotypical villain role in order to get anywhere---have ANY relationship in ANY capacity with Nanjo. And I get it. Nanjo already decided what kind of person Mok-yeon was. If he'd tried to approach him sincerely, he would've ABSOLUTELY been turned down, and that would've been even more painful.
Mok-yeon may have dug this hole, but he had no choice but to dig it.
....and now this poor guy is having a full-on mental breakdown.
I really hope his character isn't pushed into Irredeemable-territory.
Yes
