i was really hoping they will merge at the end coz well first, it is much healthy (mentally and physically) for the people in the relationship. like after they merge, they'll have this harmonized personality from the both of them. but ig this will how the story goes (really hoping for side stories to come ;-;)
p.s. even i like tae-oh more TvT

well that's not really how DID works anyway. they don't just seamlessly merge back into one "whole" person as they are two completely separate whole people already. Dongjae would have lost Tae-oh, who was his support and showed him that he deserved to be treated better so to lose him would have been devastating. both of them, separately, are mentally as healthy as they can be. they just share the body still.

i believe that they're not spoiling Jeong-Yoon coz he is the youngest or whatsoever (maybe a little), but they just don't want to shock him that they already know the truth (about him being in a relationship with Chae-Heon) and they want him, as long as he is ready, to tell them what his sexuality and his rs with Chae-Heon
you can also imagine, what if you're hiding a secret and then everybody will just come at you telling you that? if i were that, boy, i would want to just hide forever from everyone
when the art style really suits the vibes of the story and it really made the characters (esp the main leads) to be extra hot (yes I'm staring at you Callahan). also, thank goodness they're also age appropriate to add HAHAHAHAHAHA
