My Bride Is a Mermaid

When Nagasumi Michishio’s summer vacation takes an unexpected turn, he finds himself in a truly bizarre predicament. Saved from drowning by the beautiful mermaid Sun Seto, he quickly learns that her family operates under a strict code: if a human sees a mermaid, one of them must die. To avoid such a tragic outcome, Nagasumi is presented with a third, equally shocking option: marriage. Now, Nagasumi must navigate the treacherous waters of his new life, living with a Yakuza mermaid family whose traditions and expectations are as deep as the ocean itself. With Sun's overprotective father and eccentric relatives lurking at every turn, his idyllic summer retreat transforms into a hilarious and chaotic struggle for survival and, perhaps, even love.
