Thank you OtakuTrash1!
For real. Like he knows he’s in a precarious situation if he pisses off Rosa’s mom over Rosa because Rosa’s mom is who genuinely has him by the balls. She can RUIN his life. That’s like his boss who he has sex with and Rosa is the boss’s nepo kid. Rosa’s definitely confident, self-assured and kind of arrogant thanks to her upbringing but that can be attributed to her mom. If her mom decides to fuck her over she can.

Should have known the manhwa author would be a Yeonwu Hole Splitting truther because I was like thinking Oh He is quite Ukeful. He could make a nice Uke.
One can be either Uke is spirit…in essence…Like one’s aura… (regardless of whether one is dom or sub or switch) or Uke in literal terms (gay bottom) and Yeonwu fits the former…Very sensual… a je nais quois…He has the kind of sadness/melancholy in his eyes you only see in Eastern European gay porn.
And then the sex shop and the strap purchasing…Like I feel it my left nut Rosa is going to FUCK him. And here we are… A bit new to see that in a straight manhwa.
I don’t read a lot straight manhwas but I got intrigued by this one because I like the dark thousand yard stare Rosa sometimes gets in her eyes (she creeps me out deliciously) and it’s not that common to find such a psychologically tense straight manhwa with good art style (Rosa’s proportions are like wooow body but they’re also not that absurd like she just had a nice body and I also genuinely want a 3some tbh I think Rosa would love being voyeuristic and watch some hot guy fuck Yeonwu #cuckqueen but I also think she’s too possessive of Yeonwu and she’d like to be the only one fucking him…like literally his hole being only for her) . Anyway. The dynamic of societal class and upbringing could be further fleshed out as the story develops. As far as I’d like to assume Yeonwu doesn’t feel genuine love and attraction for Rosa’s mom and he probably feels very powerless in that situation but he still tries to negotiate his agency by taking advantage of Rosa’s obsession with him…to a certain a degree. Nice nice.
