10 movies/dramas with a character that refuses to see their short comings or mistakes and stay as they are, miserable & alone (even if they aren't conscious/acknowledging of these feelings). Please avoid the bad/evil guys. This is more like someone who holds on to anger, jealousy, resentment, etc.
1. Lovely Writer - no matter how many times people reached out to him, Aoey (I think), refused to change. There is a very sad, lonely scene in the last episode.
2. I Hear Your Voice - 2FL's father kept saying "I did nothing wrong" and in the end, he was alone.
