Ok, the last few chapters have convinced me: I'm aboard Nino's Runaway Train of Love. It's not just that she's refreshingly direct and knows very clearly what she wants, but she can reflect on her own actions (like how she lampshaded her previous line of "there has to be at least one girl on earth who'd love a guy like you" during her confession, or realizing that what he hated of Fuutarou was "his role", not him). She's defied the usual pitfalls since the moment she didn't let her confession go to waste.
"She's not listening at all! Even though she said she wanted advice!"
Sorry, Ichika. I understand your feelings, I really do, but your advice was self-serving. Even you'd admit that it's better for Nino if she doesn't listen to you.
