a short story with a good and simple story. a very good drawing and a short and acceptable duration. If this manga were adapted to anime, it could be a very good movie. I think the protagonist of this story is fine, it could be better, but I like it.
It could be better if some characters around the protagonist had developed in a better way, since it feels somewhat empty.
The art is good, although sometimes, it looked a bit regular, some faces looked strange. very strange.
It is a work that you can read for a very short time, to have fun and read something interesting. I personally like it because I have a great appreciation for diving, for swimming, for looking at things underwater.
