My Mother the Mermaid

Na-young works at a post office and is sick and tired of being embarrassed by her unyielding mother and pushover father. One day her father disappears without any notice; she is forced to give up her trip abroad and search for her father instead. When she arrives at her parents' hometown, Na-young is shocked to find out that she traveled back in time to meet someone she'd never expect, even in her dreams.
