1 Volume (Complete)

This was really sweet. I hope a scan group with a good translator picks it up because there were a few parts I didn't quite understand.
Summary: Yui (human) meets Kujira (merman) in the sea when they are children. Certain things happen that cause Kujira to come onto land and live with Yui. They grow up together and Kujira wants to stay with Yui, but Yui feels conflicted about this - he does love Kujira and wants to be with him but he also thinks Kujira should be with another merperson due to their long lifespans and that Kujira should explore and interact with the world. He feels he is being selfish keeping Kujira to himself.
There is also an element of fated lovers, as Yui is the only person who can hear Kujira's voice.
Overall, it's a really beautiful romance story. There are a few parts I wish had more detail (or maybe I didn't pick up on it because my Japanese sucks lol) but it's also a 1 volume book, so you can only expect so much, you know?
There is implied sex in the extra but there aren't any erotic scenes.
