Could I ask you to spoil a-bit more of the story?
What was their relationship in their first life? Why did the ML rape him? Did he even like him? Because from the MC’s dreams the person who does that to him doesn’t sound like they like him it feels like they hate him even, and did he also kill himself after the MC committed suicide?
Spoilers- this is my interpretation and it might be wrong if there was a bad translation
-In first life they got married from the start without time to get to know each other, they had bad first impressions, but they slowly got closer and start to feel like a couple, until Yido discovers SeJin stole the documents, he felt betrayed but at the same time he didn't want to let him out of his life, he later realized that what he feels is resentment because SeJin never gave an excuse, as if he's not important to SeJin, he never calls it love, but maybe obsession/possessiveness...
-The time where SeJin dreams he was giving a blowjob:
right after the reveal of betrayal, they weren't talking and when they met, Yido was drunk and angry.
-The dream where he is raped:
SeJin was raped by Yido's brother, and SeJin ran away because the brother told him he was given by Yido as a gift, it wasn't like that...
Yido was about to have his rut but forgot his suppressant, so when he went to look for SeJin he lost control and took SeJin against his will, yido also got angry because SeJin asked him the divorce and made him believe he wasn't raped but he slept with the brother to get the divorce.
In both times Yido says hurtful things to SeJin and humiliates him...
- yido killed himself but after a while, after all the traces and scent of SeJin disappeared, he thought for a long time about all the regrets he had and how he wanted to have a second chance.
After reading all the story I think Yido loved SeJin since the first life, but he felt superiority and had bad temper. Also he wanted SeJin to be happy the second time, even if it means to be apart, and he made a bond because he had feelings.
Sometimes I feel the ML doesn't suffer enough but for this one I cried for both of them at different times. Although overall SeJin had it worse...
All the time for the first half I was so afraid to how much of a dick he was his previous life to be this sweet in the new one, both of them will suffer, both of them did mistakes too... but it ends well, we will see ML pov too. Since I read with Google translation I think I missed some things, so I will stick with the webtoon...
