Finally, a chapter where she is actually a senpai for once. It really is refreshing to see the tables turning for once where Ootsuka sees his own faults and Noa being the reliable character for once.
Ngl I don't see any difference between the 3 versions of the mermaid girl. Then again I don't think we're meant to see the differences and it's more of a plot device for the chapter
It's adorable. She wants him all to herself, and she can't even bring herself to admit it to herself.
Let's hope it doesn't take long enough to become overblown.
Personally, I don't think it'd be bad to watch them evolve as a pair into a couple and see how they behave from there.
