At this point, I think it’s pretty obvious Jinwoo wouldn’t go to such lengths just because attraction alone. Taeyoung fills him. Not only physically, he gives him something he’s lacking emotionally too.
But sadly, i think taeyong still can't recognize his own feelings.
Taeyoung seems like he also have problems with his family. So in that case both jinwoo and tae need each other, not just for sex but they use sex as an excuse?
yeah it feels like they're both using each other as emotional crutches or filling a void, as @pacarkihoon said. Praying for taeyoung to have a great character development and see the light soon lol
for now he's acting at times like an 1sshole and is aware of it
tbh I think jinwoo didn't go to taeyoung only because of his attraction, his parents have been shown to be very controlling and berating his choices of studies... he's literally paying for everything himself and working to afford his studies, he's making his own path and going back to his mom for her birthday would have only subjected him to more of the same berating he always gets in their presence ever since he chose lighting (idk if that's the terme but yeah) as a career. Also he's very smart and at the edge of his rope mentally, he kept showing he's exhausted and backed in a corner with all the shit piling up on him so he needed the freedom, peace and "wild" choice taeyoung represents to him rn. like that's him going head empty and finally peaceful in a way. Not only him being attracted to taeyoung in a loving way. That's my opinion
