@Natsu_1000 Haruki is her friend and Aya doesn't see her as a love interest. Haruki is just selfish and expects a return for her supposed good deeds. She just has a hero complex. Aya for the most part did everything out of her own will.
Well fuck, she caught feels. Sei might be catching some too tho, she was calling out Aya's name first, and then she called it out when she finished. Or Aya just got really good at sex, that could be the reason too.
That monologue at the end was very sad, for both parties. Wonder how this reunion with Yoru would go. Also can't believe Yoru actually let them do it, like, there's something there
