Now, I’m not quite sure where Ao is when she passes out in the bath, leading to Takumi rescuing her and taking her home. After all, the love hotel didn’t accept high schoolers, which is why Miyabi fails to bed Takumi. Ao can’t believe Takumi hasn’t slept with scores of girls, prompting him to finally confess his virginity.
The announcement has a profound effect on Ao, as she now sees him in a totally new light. Far from fearing him as another normie man, she resolves to be nice to him since he’s a virgin, and even assumes she knows more about eroticism than him simply due to her father’s line of work.
Ao sees Takumi as so little a threat all of a sudden, she agrees to go to a restaurant to study English with him. When she later asks if he really wants her to be his first love, she ends up rhetorically and literally backed against a wall. Her whole facade of superiority collapses and she’s forced to flee in tears.
That’s when she spots Miyabi in a restaurant skulking and attaches herself to her, just like she used to when they were little kids, Ao got teased, and Miyabi was always there for her. Miyabi may have it in her head that they’re rivals now, but when push comes to groin-kick, Ao still considers her a friend.
