Aight guys, calm down. Listen to me. I think I know how this is gonna play out.
Listen. First and most crucial info that we got this chapter is Abe-chan is a lesbian too, and has a senpai gf that she got recently. Why is this relevant? Because in Tokyo, I'm 10/10 sure that Chidori and Nanoha are going to sneak around trying to get on their date behind Abe's back but ultimately busted by Abe. Abe will find this strange and say why are they hiding their relationship. She's gonna give her view on being a lesbian and BOOM, Chidori and Nanoha will realize that it's okay to let people know that they are dating.
This is all according to plan in order to progress.
Author better take this route or I'm fucking done.
