- Nakamura's reaction to Saeki's declaration that she had (forced) sex with Kasuga, which is basically "I don't give a crap." It's clear Saeki wanted Nakamura to feel betrayed and hurt like she did when Kasuga dumped her, so Saeki keeps needling Nakamura, hoping for her to break down. But Nakamura doesn't give her what she wants, even giving her a Cooldown Hug, and then Saeki breaks down instead. Then Nakamura says to her face:
Nakamura: So you finally managed to spit it out. But you've got less substance to you than a fucking fly. Someone like you could never understand, even up until your dying breath.
- Chapters 44 and 45 for Kasuga. Just... all of it. To summarize: He gives a Shut Up, Hannibal! to his past sins, crushes the symbolic Flower of Evil in his hand, and faces his demons.
