The fairy tale "The Little Mermaid" actually hides a terrifying curse. Because of the curse passed on from generation to generation, Yun Yu could not fall in love, so he could only fall in love with Tai Hao. Finally, Yun Yu left Tai Hao. But it didn't take long for Tai Hao to appear in front of Yun Yu again. Yun Yu's calm mood began to go into turbulence again... between Yun Yu who couldn't fall in love and Tai Hao who used love as a game.
