It's newtokki but for novels version. Page gets automatically translated for me. You can check this out or look if eng tl fans have picked it up or not.
So for those who are confused. Sejin was treated really bad in the past life cuz he stole something from ido for his father. And ido not knowing any better assumed Sejin chose his family over ido. Feeling betrayed N all he mistreated ido, did non con sex and the list goes on. Sejin didn't even have a nice room to live in when he stayed with ido in the past life. One day he was sick and ido's brother happen to be home cuz ido said he prepared a gift for the brother. The brother saw Sejin and thought it was the gift ido prepared for him so he raped Sejin and then Later when ido gets home he misunderstands everything and also rapes Sejin. Sejin at this point is completely broken beyond and after finding out he's pregnant he shoots himself with the pistol in ido's study. Ido realises his mistakes too late and dies(??) not too long after. Then the second timeline begins.
