Idos entire life purpose was to correct his mistakes and give sejin an actual chance. When he achieves that, he goes crazy and thinks that the only thing left for him is to kill himself cuz he cant live without sejin
of ur asking abt ido, because imprinting disappears when one of the two dies. Ido wants Sejin to be free hence, why he'd kill himself so Sejin's not bound to him anymore. And other than that he regrets all what he did on the first timeline
I wonder what makes him want to die tho?
