Furthermore he hasn't actually helped a single heroine in the story.
Aoi - he cheated on her and made her suffer
Yu - He knows that she is is suffering from something but didn't do anything just so that he will have his sanctuary.
Tsuyako - he realized at some point that she is worrying about something but ignored it so that he will have his "accomplice".
Saffron - he already realized the meaning of the name "Saffron" but didn't say anything except have Saffron console him and not the reverse
Asa - he knows Asa is chained by him and his promise however until the very end he didn't sit her free.
Sora - he should have wonder what Sora's deal is. After all someone like her must be guilty by something if she casually give herself away like that.

He has many girls however he never truly understand them. And he just indulge in their affection. And they just comfort with each other without fixing anything.


That is why I like Koremitsu alot better after all he has no pretense of what he is. And didn't just comfort them instead he fix their problem and saved them.
