yeah. but he is not completely gone. so his actions are not really excusable. he is sane. he is just sometimes on his own too much in his head. because he has no one he wants to listen to. but kyunsoo was so intriguing he let him in, so his words had meaning for him and not like everyone elses words that he didn't even listen to. his actions are not excusable. just because you are in pain, does not allow you to cause pain for others...

Ok, hear me out I don’t like him but he doesn’t deserve this. He’s literally mentally unstable and needs help.
