They all suck, and that's what makes it good.

They are all terrible people, and that's what I love about them. They're all true to humanity, selfish, careless, idiots, and you can't help but care about them. This was really a plot twist that carried so much weight but didn't negatively affect the story. It showed their true personalities and what they could do to be selfish. They are all assholes and I love it. No one is lovable, everyone is a liar, desperation can lead to despair, but the story slaps.
Seno is a liar/manipulator, Natsuka is a selfish asshole who can't notice anything else but the one he's aiming for and the goal he's set for himself, and Hakushima spoils himself to no return. I'm glad natsuka and seno got together bc it thwarted my expectations, but it also showed effort of how selfish people can be. It drove the story, this isn't only a cute love story it's one about lies.
