- Ho Yay: Sei and Kai.
- Les Yay: Ichika and Manatsu. It's rather subtle, until Manatsu kisses Ichika. In the manga, Michiru obviously has a thing for Ichika. Keiko and Satsuki get their moments as well, which even survives them quarreling over the same guy.
- Moe: Ichika.
- Moral Event Horizon: Saya crossed it before with her "test" and Sadistic Choice, and does it again by putting Ichika in the same situation.
- Tear Jerker: So much.
