I see a lot of people saying this and I get it I really do but shit man it's been 4 years and he went to the military so ofc he's not gonna be the same bc he's more mature now; also, maybe he u know actually realized his methods were dumb and that's why he didn't get the guy so he's doing something different; if he behaved the exact same way with both mc's poeple would definitely think he's a player and doubt his sincerity and for good a reason lmao; I actually like this bc yeonwoo and wooyeon are two different people and I think he specifically doesn't act this way around wooyeon bc he already knows wooyeon likes him and wants to be with him, but it's just a matter of having a younger bf so he wants him to be comfortable with him- he's not outright in his actions but he is needy and affectionate! he's always up in wooyeon's space and touching him and he wants wooyeon's attention all on him! even in the early chapters he's pissed bc wooyeon avoids him and goes to look for him in the rain and when the bully is bothering wooyeon he comes right away and at the drinking party after exams he gets garam to leave so he can sit with him!
EXACTLY. and from the novel we know hes more reliant and comfortable with wooyeon than anyone else even before because he doesn't desperately have to seek his attention due to being an orphan and his trauma there which holds him back from relying on being more real to wooyeon out of fear of loving him more than being loved, it all comes naturally and ofc, he's excessively affectionate after figuring things out haha

What bothers me is that we know the ML is actually so affectionate and like a needy puppy when it comes to the other omega i forgot his name. U can tell this is all just an act. Im looking forward to the chasing arc and I better hope MC doesn't fold too quick, I like the drama ლ(´ڡ`ლ)
