Huh??? I am so confused. What chapter are you even on? Also hard disagree. MC just trying to survive. Is it opportunistic perhaps? Sure. But in the end no one here is without flaws, and that's part of why I like this manwha despite the art not being my favorite style.
These relationships are almost all toxic and complicated. Even his roomie/true lovebird gets lied to, whether for convenience or protection. No one here is the hero.
Hope you find a new series that floats your boat! There's so many out there

MC had sex with different guys. Totally ruined the mood for me.
