Small scare at the start, but ends up being more intel for our passenger group. And oh boy, Nayu fantasizing her dream date with Hikoichi. Come on boy, she's hinting to you how to approach her.
Now given Hikoichi gets on the train before Nayu and also gets off the train before her, this may be a first that he sees how she behaves at baseline in casual conversation. Nayu's already gotten a few times she's seen Hikoichi at his baseline that further fueled her interest in him. So we're steadily building that foundation for when the clutch time comes.
