Shouya looking at us like that was really hot. I'm even half-convinced Mitsuki blushed in the next panel not necessarily just because he was threatened. Would be funny if they made a switch and he became Umi's "rival" for Shouya's attention
Mitsuki's mindset is something else lol
On the topic of Umi's mom being overprotective, is she really? I wouldn't be worried about a sixteen years old living in a school dorm or something, but in a house or an apartment by themselves seems a bit much. Although there is quite a few manga where it is the case.
