I agree
Those 'loyal' readers gonna say that Ido acted like that because he feel guilty to be happy with Sejin buf can't bear not to have Sejin in his life. This ja just glorifying Ido's incompetence and selfishness. He want to make Sejin happy and acted sweet around him. Then the guilt comes, he will just abandoned the moment because he feel like didn't deserve it. Dude is sure selfish. He only make amends to relieve himself, not for Sejin. Because, to make Sejin happy and thriving, I do doesn't need to be physically present. He could help, guide, and support Sejin from afar. He truly didn't need to show himself.
I agree with this too
i actually dont care if what hes doing "behind the scenes" will end up being sweet and thoughtful later. does he not realise how bad he's hurting him? you found him in your next life... after being so horrible to him that he took his own life... and you still wont even put in the effort to make him feel loved? like hes done nothing really wrong per say and i can understand that him missing every important fucking event may be because hes doing something bigger. but like a heads up would be nice. maybe a "hey sorry baby i cant make it love u." instead of making him wait anxiously for u just for u not to come at all. even a little smile would be fucking nice u dickhead. sejin is actually so strong cause i wouldve ended myself for the second time by now.
