Everyone's harshing on the dolphin for being an asshole, but I think we all know people can be assholes too.
More specifically, we've been known to be complete assholes to dolphins.
The way I see things, it's kind of impressive that the bottlenose dolphin isn't holding more of a grudge against humans in general.

This seems so familiar, but I can't find the prequel.
Does anyone know if this is based on an earlier story and, if so, what the title of the original story is?

I think what y'all searching for be this http://www.mangago.zone/read-manga/tenjou_no_shita_ni_koi/

The more I read the more I think I read about this couple somewhere before... Maybe because of the art? Idk...

This author doesn't waste a lot of time on plot development...
It's just, let's go for a walk, then straight to I love so let's bang.

Well I guess he wasn't going for a shounen-ai type of manga...
Honestly what did you expect?

I wasn't "expecting" anything.
I was merely making an observation.
And being tagged yaoi does not mean it's all sex and no story.
Yaoi is separated from shounen-ai because it contains graphic sex scenes, not because the stories are any more or less involved.
Mangas that are all sex with very little plot typically get a "smut" tag.
More importantly, why are you being so pissy?
Comments aren't just for gushing over how great everything is.
I had to keep reminding myself that "she" was a he because if you weren't already clued into the fact that the host was male, you could have missed it.
Even in the sex scenes he looked a lot like a woman, for example:
