Saying that in front of Hina is foul bro

Well.. You're right, but I thought she already settled down and moved on? :(
It also hurts if the one you think of as an ally (Moriya) also think the same as others (another girl hovering around your guy is annoying and not relaxing at all) when she was the one who supports Hina the most when she was rejected and knew that Hina is still hovering around Taiki before and after he and Chinatsu became a couple.
So he was inside of minchan in every way
