That’s when MC proposed a divorce! That’s right they were married in their past life—not engaged. Ido was triggered and didn’t want a divorce so at the heat of the moment he also raped him and marked him. Sejin got depressed and decided to kill himself using the gun in Ido's study infront of Ido. Ido also killed himself afterwards. Also the reason why, Ido took out the bullets of the gun and prohibited Sejin from entering his study in this current one . Then they get a second chance in life in which Ido remembers everything and tries to make up for him being a piece of sh** in their first life. Sejin remembers part of their first life to dreams because Ido imprinted him before he died , when you're imprinted you the share memories and emotions of your partner.So that's what basically happened though I don't know if he loves him or he is treating  him kindly cause of guilt , if you see in 1st few chapters it shows that sejin is getting raped by someone and that was his past .hopefully that explains it .😊
