MY Cursed Merman Prince

Prince Adrian, the chubby merman prince, embarrasses himself after a confession and makes a wish to the Conch Spirit to become handsome and slim. Gaining widespread admiration, he grows increasingly terrified of losing Cassian, so he makes a second wish: for Cassian to see no one but him. As sweet affection turns into surveillance, imprisonment and dangerous possessiveness, Adrian must abandon the love bought by magic. Meanwhile, Cyrus, his cousin who covets the throne, plans to seize the final wish.
