He still won’t forgive himself even after Sejin forgave him and got together. The Novel ended with Sejin talking to Ido about seeing a therapist. Because Ido is suffering from depression. PTSD and is suicidal. He loathes himself to the point he thinks he doesn’t deserve to be loved by Sejin. They are already planning their wedding and still he thinks he doesn’t deserve the happiness he’s feeling of being with Sejin and getting married to him. But Sejin told him that “Beyond that memories we are happy.” It was an open ending but realistic. Because recovering from mental health issues doesn’t happen overnight. One might be forgiven by the people they wronged at but not by their owmself. Forgiveness for yourself is very difficult than asking for a forgiveness from other people.
And I admire the author for showing us how mental health issues can destroy us even when we are supposed to be in our happy state.
Part of me did hate ido but he tried to change or even correct his mistakes from his last timeline. He probably got to know he messed up after mc died. He got to know the truth. And he decided to change the future by helping seeing to be independent emotionally and financially and also physically. He even sent that bodyguard to keep him safe. He made sure his piece of shit father was in jail. Because of him actual mess was started in 1st timeline. He knew he won't be able to forgive himself unless sejin does.
