I don't know, but i can see that wonho actually really loves minki °Д°

Its not that its healthy for the 2 of them to stay together, nor that the thing they are having is a "relationship", its just that he does seem that he cares about him, even thought that he is what he is. And since you said, I personally am an adult and in a long term relationship, I wouldnt like or even let anyone treat me like he treats Min-ki, but its just an opinion on the comic character, people shoudnt find it so personal and real life like.

He doesn't "care" about him, he just wants to posses and control him, he's an narcissistic egomaniac who thinks he can go fuck whoever he wants but if the one person he's steadily hooked up with out of all the others for years does anything with anyone else he beats the shit out of him and treats him like trash. He's the definition of a toxic, chronic abuser and by no means does he actually care about Minki. He cares about him in a sense that by forcing someone to stay subservient only to him and no one else, it boosts his ego and that person falling for anyone else hurts his pride so he physically hurts him. Wonho is such a sociopath I doubt he actually cares for anyone at all other than himself and any manipulative bullshit he might pull when he thinks he's losing the person he keeps under his boot to fall back on is just that, manipulation for his own gain and nothing more.

I dont get the uke? He likes that senpai, but he also keep rejecting and push away the senpai, or did i get it wrong? Based on raw °Д°

it's exactly as you say but if the sempai liked back the uke (or at last not for now), but the sempai after being confessed to said to the uke "you're disgusting", and rejected the uke every day, because he isn't interested in the same sex relationship, than me too would keep rejecting and pushing away the sempai because i would be very scared and insecure, to love someone without being reciprocated does not mean that you have to have sex with him and be happy knowing that you have nothing in return, i think is very sad and the uke probably knows it, this surely is the reason why he refuses the sempai
