Amnesiac mermaid Celine was rescued by Leon from the seaside, only to find herself trapped by his obsessive confinement. Leon, scarred by childhood trauma, feared abandonment and sought to maintain their relationship through control. Celine eventually recovered her queenly memories, feigned weakness, and skillfully strategized. Leon had a sudden realization and, with a heavy heart, returned her to the sea. However, Celine, already deeply bound to him, transformed into human form and returned to land. Their roles completely reversed; this time, it was her turn to firmly ensnare Leon.
