The art is nice ESPECIALLY the way the jellyfish is drawn however I dropped this manga because I could not get past the fact that the jellyfish is the MC's grandpa past lover and now it's his lover....Excuse you what? They said "let's keep it in the family and all share the same hole" Woah, but aside from that the MC isn't a lovable character, he is a playboy who sleeps around with plenty women and at first doesn't believe the jellyfish and just thinks it's some random guy who broke into his house. Another thing that made this weird is he sees the ML/ukeas a "kid" he called him a kid when he saw him outside, but the fact that the MC is a full grown adult and he is supposed to fall in love with him who he sees as a kid is also weird.

This could have been super cute, but instead the writer decided to make his grandpas first love now the MC's first love. What!??
