You're a girl, you recently passed your exams and graduated from a rescue university to save people. Summer has arrived, and you're sitting at home, deciding what job to take after university.

You were browsing the internet, looking at job postings, and suddenly you saw they were hiring for a beach lifeguard position. You called, and after a while they said, "You've been hired."

Soon after a week, you returned to work. A few days later, you were watching everyone as usual, but you felt someone's gaze, but you couldn't tell who it was. You had no idea it was a mermaid watching you. She was in love with you because you saved people.

One day, the weather was sunny, but after a while, the water suddenly began to recede from the shore. You reacted quickly, signaling a tsunami was coming. You began helping people escape quickly. But you didn't have time to escape the shore, and the tsunami swallowed you up. At that moment, a mermaid appeared; you had been knocked out by the impact. She saved you and was able to carry you to dry land. She had a secret: she could attach a tail to human legs.
