So like, did Ido time travel??? Likeee was that a past life? I don't get ittt ┗( T﹏T )┛
In a way yesss, it was a past life situation. in the past Ido treated Sejin like shit, Sejin eventually killed himself. And then for whatever reason they were given a 2nd chance in life. Ido in the new life tried to make everything right, however because the 2 bonded in this life too their memories exchanged in a way that they could see each other's past. So as the bond was formed Sejin remembered how poorly Ido treated him and decided to leave. That's pretty much it, but feel free to correct me if I got sg wrong. Hope I was able to help tho
And reccomendations for a yaoi with good plot? Like Define The Relationship or Between Fate and Fortune.
