Fairy Tale Mermaid

The male protagonist with a grumpy personality dressed up as a mermaid. The setting is that he has a pair of normal teeth and a pair of good teeth like jagged teeth. He does not know the story of the mermaid. The CP is the sea wizard octopus monster. He is the male protagonist's crazy fan, but the male protagonist does not love him, and then he predicts the future of the little mermaid. The male protagonist is the only heir to the mermaid kingdom. He likes to collect human things (very useful). When he was sixteen, he had to float to the surface to be baptized by the moonlight. He saved a prince and asked the octopus monster for a potion that could turn its tail into legs (actually, the male protagonist just got tired of eating fish and wanted to go ashore for a change). But in the eyes of the following wizard, this is a prophecy that is slowly coming true! No! In order to prevent the one he loved from turning into a bubble, the wizard proposed harsh exchange conditions to the prince. Then the male protagonist stepped on the wizard's head and said, "Whose territory do you think you are living on, how dare you make demands of me." Ah, author, I just want to write such a cute (sickness) story. I still focus on novels, and I just love focusing on them. Conception:
