At first I was shocked when Maekawa uttered the name Makoto cause usually that's a male name. But then I remembered that's Shimizu's first name... big sigh of relief
I was like "wait, who's Makoto again?" for a second the first time around too. I don't even remember Maekawa's first name, if it's even been in the manga yet.
That name is one of the ones used for both sexes. Akira, Hinata, Haru, there are actually a fair number more. I was reading something online about it and apparently there are names common with older guys that we now associate with women too. It's interesting to me how names turn over over time.
