Art is great, but the MMC feels rather insufferable right now with how pathetic and wallowing in self-pity he is. Seems to have had no mental development in the years since his school days. Urgently needs some redeeming qualities to make him interesting as a character based in himself, not just because he's the inexplicable object of interest of a girl. That shit may work in his hentai, but a normal story needs better charaterisation of the protagonists.
