Bro what are you even talking about?I've lost most enthusiasm for this series.
Kerori has all but lost Best Girl status due to the diminishment of her precious glasses.
Only Mar-chan and Miky-chan remain as Best Girls, and they're supporting cast and side-villain respectively.
The harem element was always a part of the story. You do realize the MC's group is basically a 3 member polycule of platonic lovers at this point like he even calls them soulmates. Plus there are many women and men aiming for him.Oh no. Dumbass harem drama. And this story was good too, now it's moving towards becoming trash.
