I will call it, THE MC IS TRASH, I understand that he is not honest with his feelings just like Mizuhara and that cowardness and uncertainty are basically the main traits of his personality, but dammit! I think that he is a bad person, the way he is treating Ruka is unjustified, is he just going to go to a trip with her even though that he doesn't consider her like his girlfriend? Then what? Throw the bucket on her feelings when he becomes Mizuhara official's boyfriend? That's like he is exploiting her.
