@ryouhira it be called character growth and development. plus, this is a slice of life romance comedy. It is kinda meant to have an episodic feel to it
without clear reason how they decide to visit pool, i can't feel the development in this chapter.
at least make a scene when they invite her or something like that!
ah yes, a pool chapter. of course. though, we didn’t even get to see a chapter before this where the three of them talked about going to the pool and all. author???
