I REALLY HOPED that he would have at least restarted his therapy sessions before going into the relationship with Inseob, no matter how many years that took; and it would have been better to show that journey. People who have mental health disorders cannot be cured, they just get better (but it's still there), they will be in rehabilitation, forever.
This is not a way to defend the top. The reason why a lot of people cannot comprehend the shift in the top's attitude is because his mental disorder was revealed very late in the manhwa and there is little explanation to it. It could also be that the readers don't know a lot about the disorder. But, if you research more about it, those actions will make sense and as to why he acts like that, ESPECIALLY, for someone who has not had therapy for a long time and just constant medication (I' not even sure about this one).
