it's a HEA, don't worry.
take with a grain of salt bc my understanding of korean is rudimentary at best:
after this chapter the "fake" hyung gets angry then cries when jinsung tells him to switch with the "real" him and questions why it wasn't him that made him fall in love and says how terrifying and lonely it is inside his mind when he's "asleep".
and despite jinsung saying he would love every part of him, he still looks for the 'day' hyung more. this fuels the 'night' hyung's insecurities because- plot twist, he's the real-or rather the original personality and the perfect and kind hyung was the alter ego he made up because he wanted jinsung to like him and he was ashamed of who he was and how he fantasized about jinsung.
he's pleads with jinsung like, "look at me. it's the same face. so please don't hate me so much" and "what should i do? should i laugh more? i won't touch you anymore. will it be okay if i go back to the way before?" (lowkey unhinged lol bc he still had his dingdong inside him)
and there was a fundamental shift in the 'night' hyung's demeanor compared to his flippant attitude before that jinsung realizes they were essentially one and the same and hugs him. he becomes unable to distinguish between the night and day hyung anymore.
next chapter is of the night hyung's monologue and recollections. he do be fighting some demons in his head. it ends with a eureka moment of sorts where in admitting his feelings for jinsung in both the night and day versions and jinsung accepting and loving him as a whole, the night and day merges and memories flow into him.
he recalls a day where he came home messed up and covered in bruises, but young jinsung takes his hand and offers to stay with him without hesitation anyway.
so yeah, jinsung wakes up to this and starts crying from relief bc all this time he thought he was making things worse for him by keeping it a secret etc. etc. but he apologizes to Jinsung instead for all the stuff so far & says "Thank you for waiting until I can love you properly."
Later chapters+extras are hilarious and steamy because they're both jumpy af about the sex part of their relationship. They both want to do the deed but are too shy to initiate, and a couple more kinks are introduced.
:'( like for sure both personalities love him and lust over him, both of them want to exist and be with him
