I was quite sure from early on that he was meant to like Akari, because the way their relationship was written out is slightly different from the others.
But looking at how this is going, it doesn’t really seem like the girls are being considerate to each other’s feelings and the dynamics of the group.
So bro, just fuck it. They want to be selfish, the. You deserve to too. In reality, the girls would have ruined the friend group themselves. So might as well go ahead and date Akari already.
