Nah, I would disagree tho. As rough as Taesung is, at least he didn't rape Sooyung, doesn't really have sex with other people, and excluding some certain specific things, he's pretty much honest with Sooyung, not to mention Sooyung likes it and his feelings for him is mutual as well. Both are cut from the same cloth but they're quite different from each other.
I mean Sooyung looks like he's fighting for his life every time they have sex. And he constantly begs Taesung to stop. They are definitely not on the same level but he's not a good guy either. He's scary and uses intimidation to get what he wants, he is having sex with someone who is in a position of authority over him (not in a “hot” way).
Sooyung is not afraid to beat up anyone he doesn't like. He's not afraid even if his opponent is bigger than him. He bitchslapped his ex who was way bigger than him. Heck he even brawled with Taesung when they first met. Even with all of that we don't see Sooyung try to hit Taesung when they have sex. He doesn't even try to slap him. He likes it but he's in denial about it. He's a closeted mild masochist. Even he himself would say that why am I enjoying this or why does it feel good.
Taesung is not a good guy, he's literally a gangster boss. But for a supposed ruthless gangster boss, he's quite "gentle" to Sooyung, relatively speaking.
I remember when taesung threatened to break his functional leg and Sooyung visibly looked scared and terrified of that thought, so I wouldn't say he didn't give a shit, intimidation definitely does play a role in the relationship. Understand where you're coming from but in your initial comment you made taesung sound like he was all great, main reason why I commented.
My bad I may have missed spoked. I re-read the chapter real quick to refresh my memory he didn't exactly look terrified, he dozed off while the threat was being expressed to him so he didn’t pay attention (was still staring at his wound), he looked very dead inside though in that panel. But it’s still a good example on how authority and intimidation does still play a role in keeping sooyung around.
Just read chapter 52 and damn Min-hyuk clearly raped the mc cause he knows the mc wasn't on the right mind but he took advantage of it (● ̄(エ) ̄●) can we all just agree that there is no one much better between Tae-seung and Min-hyuk cause they are both cutted from the same cloth
