This chapter was really rushed...
Still not sold on the Rin/Akira side because becoming gfs just to prevent Akira from being unhappy isn't a good enough reason....I just can't see their chemistry as romantic partners yet. I like them as friends, but I'd like to see Rin actually be attracted to Akira too before dating.
Unfortunately from her back story I had a feeling it'd end up like this anyway (where Rin will just go along in a poly relationship without romantic feelings for one side). I know there are polygamous relationships where it's not like everyone loves each other equally and it's more like two partners loving a single person, but still do romantic actions with each other, etc, but yeah I'm just not sold on their poly end yet. I have a feeling I will remain unsold if Canno is truly rushing the end :/
