I wasn't shipping that idiot Minami with anyone, but actually he should go for Endou. Why not? Endou seems to like him well enough, so it could happen for her sake.
Nana might want to switch to Ibuki again if he wants a more mature man. Ibuki isn't such an edgelord anymore, so it should be fine. Although he will go back to Netherlands, so I guess it's no good. She doesn't look like she could just keep waiting and waiting like Haruka.
