So every dream/ hallucination that Sejin sees in this second life are memories of his first life ( past life). Sejin died because he killed himself. Sejin and Ido's relationship in the first life is not good as you can see from the flashbacks/ dreams/ hallucinations of Sejin. Everything went down a spiral when Sejin stole data from Seonho which parallels the current chapter in their second life rn. Sejin was also r*ped, knotted and imprinted by Ido in the first life then afterwards Ido's older brother did the same to him, thinking Sejin was the "gift" Ido told him to get at his house during that time Sejin was in heat by coincidence and Ido's older brother is known to assault omegas. Sejin wasn't really the gift Ido mentioned but dumbass didn't think Sejin would encounter his brother that day.
Sejin was raped by Ido’s brother it happened during the chairman’s burial so nobody’s at the mansion. Ido’s brother went there bec Ido said he have a gift for him. This is the time Ido started neglecting MC nobody in the mansion was allowed to talk w/ MC. It was a coincidence at that time MC was also in heat, so the ra** happened. MC called up secretary Kim and want to leave Ido’s Mansion. Fast forward 3 days later Ido went to MC’s house not the main house, but MC’s own house. Ido already knows MC was raped and wants to take him back to the Mansion. Then Sejin found out he was pregnant he wasn't sure who the father was since he was assaulted by 2 person in a short amount of time.
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 .😊
