Not sure. I'm guessing it's Hyesung, the dark-haired one. Haise
Cuz like he kinda has a lot of scenes from the first couple and you can really see his personality switch when it comes to Taeyang and he's probably even aware of it.
meh me personally i think its more on a physical level cuz its not cute in the sense that they don't stare longingly into eachothers eyes lmao but it definitely depends on who is reading and what they think
It's the uke who fell first (but for some reason, it feels like they fell in love together) but the seme realized his feelings late. I could say it's almost similar as for the redemption arc but it's more good than that one XD
PLSS UPDATE
