During his summer vacation, middle school student Nagasumi Michishio travels to the Seto Inland Sea. One day, while swimming at Mio Sun Beach, his leg suddenly cramps. No one is close enough to notice his desperate screams for help, and so he sinks into the ocean, where he is left to drown alone. Just as he loses consciousness, however, a mermaid appears and saves his life.

That night, Nagasumi is visited by his savior, a girl who introduces herself as Sun Seto—a mermaid from a yakuza family. As it turns out, under mermaid law, a mermaid whose identity is revealed to a human must be punished by execution. To avoid this harrowing outcome, the Seto family propose a solution: Nagasumi must marry Sun or die at the hands of Gouzaburou, Sun's father and boss of the Seto clan. Faced with no other option, Nagasumi takes her hand in marriage.

Now, the newlyweds face the difficult task of keeping their relationship secret. Between Gouzaburou's unending attempts on Nagasumi's life and the eccentric antics of a slew of antagonists, a genuine and innocent love blossoms between the pair as they adapt to their new life.

While on vacation a middle schooler was saved from drowning by a lovely mermaid.

Who is the daughter of a Yakuza mob boss.

Also there is a code about mermaids never being found out by humans so reason reason reason they are engaged now and she's moved in. So the exact set up of " Urusei Yatsura" only more romantic and less fanservicy.

The rest of show is a mix of romance & comedy as everyone is in love with either the MC or the mermaid and trying to win them over while the couple stay glued together.

While the original show and manga were fine ...

Mixed Feelings
I want to warn some people because people might have wrong expectations. In general I like this type of comedy but still it was one of the worst I ever seen because of main character and his family. Main problem? There is huge focus on suffering without enough mitigation measures. Main hero want but can't escape from hardcore bullying and in general suffering that grows and at some point push him to think about suicide which actually wouldn't be so unreasonable in such situation... In most comedies in such circumstances at least main hero is just immune or almost immune to pain or at least ...

There was one moment I vividly remember from this show that nearly had me crying from how hard I was laughing. It was that one moment that kept me painfully crawling towards the final episode, only to be left disappointed.

The premise is interesting enough. The characters aren't great, but you don't always need great characters for an enjoyable piece of entertainment (I am much more forgiving of this in comedy shows in particular). Save that one joke that beautifully stuck the landing, I just did not have the same sense of humor as the writers did. One particular gag (that unfortunately recurred throughout ...
