No it doesn't justify the rape. But he still is better ml than most other yaoi's. They be raping the mc left and right since the beginning of the stories and people still don't blame them lol. That's why i said idc what anyone thinks. From my pov, he's better than most ( minus the rape he did in the latest chapter where sejin thought ido knew he was raped but what ido knew was sejin intentionally slept with his brother, however, that was indeed a rape)

Additional info : Ido's brother wasn’t meant to visit his house that say. Ido Didn't like his brother even in the first tl, from what i could say. Anyways the gift thing was probably something business related ( i didnt pay much attention) and his Brother was meant to visit when ido was at home, so the dates got changed his scum of a brother thought sejin was gift ( he was a pervert thru and thru and he got what he deserved at the end).
And if anyone wanna know any further spoiler,
Ido killed Himself right after sejin died.

You can use auto translation to read it
I read the novel but there wasn’t a version of Ido's pov ( or at least i didn't find it) but if you think from ido's pov, he married someone he never met before because his family was kinda blackmailed by sejin's father into the marriage, and after he marries him, he somehow did in fact fell for sejin. But then sejin stole those documents from him for his father, and in the novel it was quite specific that he got mad at sejin Because he had quite a lot of time to confess that he took those documents, but he didnt and that only proves how much sejin Didn't trust ido. That's why ido was mad. During their cold period, he suddenly learned that Sejin is missing and he slept with his brother ( Sejin wasnt the gift ido's brother was mentioning, it was something insignificant), so he Thought sejin slept with his brother intentionally to piss him off.
And only after bonding with him did he finally get sejin's circumstances. And he would beg every night to sejin while he(sejin) slept. He was ignoring sejin Because he was so guilty he couldn’t face him. That guilt followed him in 2nd timeline.
So idc what you guys say, they're just a victim of misunderstanding.
