COMPLETE SPOILERS
alright so from this moment on, juyeol begins to lean on taeyang more & they share many cute moments together -- that of a normal couple while it not being established. all is well between them & juyeol is much nicer until one day taeyang receives a photo from someone of juyeol's undressed back, sitting on a bed. this person is the model we met in chapter 6 (kang min-geon) taeyang runs home, juyeol, not knowing what he's seen, goes to juyeol's house & taeyang tells him off, shows him the photo, & runs off to some club. juyeol's wife hired some men to take taeyang & bring them to her place, where she threatens juyeol to stay away from juyeol because she doesn't want to be caught in the crossfire. juyeol finds out about this & he is PISSED & the next time he & taeyang meet, taeyang starts a fight & juyeol says some cruel things which lead to taeyang saying he wants to stop this arrangement & juyeol drags him back & forces himself onto taeyang. immediately he regrets it & is panicking over what taeyang will say when he wakes up. he goes to the convenience story to buy taeyang medicine & food but by the time he comes back, taeyang is gone. from here, we are at chapter 65 & on. juyeol visits taeyang house, sees that harim is there, & has enough shame to turn back around & leave them be (without them noticing). juyeol receives a photo from when taeyang was at the club & some guy is on him (it's made to seem like something weird was happening, but it was nothing) juyeol immediately goes home & asks for a divorce, then we find out juyeol was helping taeyangs mom out financially without his knowledge. next chapter, juyeol is waiting for taeyang outside his house, he can't even look him in the eye. taeyang tells him to go away & juyeol is begging for another chance so taeyang says he'll take him back if he's allowed to see other people too, thinking he'll say no. juyeol suddenly bursts into tears & taeyang just leaves him there. then on a reporters mission, taeyang goes into a hotel & into some vip lounge where he finds the model who sent him those photos. the model drugs him & he tries to assault taeyang & juyeol finds out & goes to save him before anything happens. he is saved but they get into an argument & juyeol is yelling at taeyang & turning this whole thing into a lecture. taeyang is offended & says something along the lines of "shouldn't you ask if i'm okay first? why did you come if you were going to be this way?" & he's dragged away from the ashamed juyeol by harim. taeyang is in the hospital & juyeol apologizes while he believes taeyang is asleep & explains himself. taeyang gets out of the hospital & juyeol follows him home where he meets his mother & she tells juyeol how happy she is he's there to care for taeyang since he's been so depressed after losing his horribly cruel ex boyfriend & juyeol looks guilty as hell. juyeol stays sitting outside taeyang house all day while he sleeps with the flowers he bought taeyang next to him. taeyang seems him, yells & him, juyeol apologizes again, & they talk outside. taeyang says he'll let juyeol back into his life, but that he doesn't want to date right away, & juyeol is grateful & says okay. next chapter, juyeol is helping taeyang move out & juyeol hands taeyang a bouquet in his kitchen & taeyang kisses him & it ends with them hugging & smiling.
I apologize if this summery sounds a bit weird, I tried to be as explicit as possible & used their names often so there is no room for confusion.

Is there a chase arc because this ml is so annoying bro
