someone pls give me a summary of what’s going down in the flashbacks cus i refuse to read them

That's a spoiler. We haven't gotten that far yet. What we know so far (at least what I remember) is that things were going pretty well for a while, then past Ido found out about Sejin's betrayal and started ignoring him. I think at one point Sejin started begging kinda and then past Ido forced him to suck him off. Then Ido is absent (business trip or he just doesn't come home idk), Sejin goes in heat. The brother comes and violates Sejin, saying he didn't expect this kind of gift from Ido (I read in a comment that Ido was saying the gift thing sarcastically and had a bunch of papers in his study containing brother's downfall for him to find). After it's over, Sejin gets dressed and calls Mr. Kim to drive him to his own apartment, where he takes sleeping pills to basically sleep the heat and his pain away. Then, Ido comes and chastises Sejin or smth, unaware of the situation. He then sees Sejin's wounds and Sejin says he wants a divorce. Ido says no and ridicules him. Sejin then basically says he'll sleep with his brother however often he must, he just wants to get divorced pls. The chapter ends with "That's right, I slept with your brother." or something similar.
And I guess the things the other comment talked about will happen in the next chapter(s).
if one of them dies i’m literally going to spiral n crash out
