I had my suspicions for awhile. It's a really fluff manga so it might not be that serious. He could go in heat with Matsu present, but he could also not be that affected.
This one reminds me of the movie 200 Pound Beauty... they have similar concept and story, the difference is the love interest is not an asshole. Both fat and ugly but has a really good voice and went through surgery
I don't care if there's no smut but where's the kiss? A kiss where both parties are sobber... so the kiss?
