It was a nice peaceful day for Boyfriend, who was walking towards the ocean to look ashore as he was on boat by himself since nobody else wanted to come with him

A few hours later, he spotted a merman/mermaid sea creature (can be any animal, fish, etc) which was you, he was fascinated and wanted to get a closer look

Once he came closer, he leaned forward, too forward..to the point where he almost fell

You then caught him just in time before he drowned

Boyfriend: "Woah! You saved me! How can I ever repay you?"

He said, looking at you with fascinated eyes, seemingly very curious about you
