I've been waiting weeks for 209 to be translated because I wanted to know if there was gonna be a poly reveal to their relationship. Like I thought that mahiru was gonna be revealed to have a crush on both mahiro and yuu and that yuu had fallen for both mahimahi's and was scared of upsetting mari for not being totally loyal to her. Then maybe mari and mahimahi would be willing to get with each other because none of seem against the idea. Like it just hadn't crossed their minds before.
Guess I was wrong.
Screw it i'll just keep my fingers crossed and hope that it happens someday. Look back at all their interactions and tell me a 4 way poly relationship wouldn't work.
