Yes, at some point, the uke felt that the behavior of the ml was not the same as before and that there was something different...
even while spending the heat together, he felt that there was a difference, the treatment, the touches and the smell resembled his deceased friend who he had previously loved (I doubt it),but he was denying this and trying not to think about it.....
and some things happened and the ML decided to confess, and when he told him,
the MC was very happy and cried a lot and told him that he had a feeling about it, and later the ml told his friend and family about it.....
and they had a child who looked like his previous self and the ending was happy, and of course ridiculous....
And yes, The silver hair is really strange... It's not that the MC is cheating, but it's simply considered Betrayal of a different kind, but the ml only cared about the selfish MC who lives the role of the victim....
He didn't care about himself or his body that he lost.. He really is very stupid. ...
Anyway, the story is not long and ends with 30 chapters, and I didn't really like it.... It just makes you feel bad ..

It's not about self-respect. He loves Sae-In with all of his heart. He came back to propose to him only to find out Sae-In had already been marked. And once reincarnated/took over the body of JaeKyung, what was he gonna do? Just completely forget about his love? They knew each other for a long time. And he loves him. He wasn't about to give up on him. And In Jun's brother says that whatever In Jun sets his mind on he will relentlessly pursue it until the end.

It is about self respect. He died saving him n tbh as a reader I didn't even see saein reminiscing about his friend more than once, maybe it's the writing but I couldn't really see his sorrow. Also, I get that he's a simp in love so he won't leave saein alone but let's just say I thought he deserved someone who reciprocated the intensity of his feelings. They're together coz it's convenient, the story is just convenient and the plot is based on luck of the ml who got to swap souls. Good for him if he's content with that I guess. Anyway I didn't take this too seriously but just thought I'd reply to you.

I'll see how the rest of the story unfolds before making the final judgement on Sae-In.
There are a lot of reasons for my reservations. 1. Sae-In's mind being weak. 2. Sae-In being manipulated and forced into having sex while passed-out drunk 3. Not having anyone to rely on. 4. My own life experiences.
I finished reading the story...
after uke received a lot of hate, the author explained that the two were not dating...
however, I just hated uke until the end, his friend died saving him and this caused him to shed some tears in his condolence, even his guilt did not It takes a long time and he was just trying to ignore it and live with that person,....
of course it ended with a happy ending (of course not for me)...
The uke doesn't deserve this happinese ...
He was selfish and disgusting and made loneliness a reason to do that even if they were not dating , it was more like that...
