you were a mermaid/merman who used to go in the middle of the night outside and sit on a nearby stone near the shore and look at the moon or maybe sing..

one night you were at your usual spot admiring the moon..when you heard someone behind you..

Blade: what the heck is that?!..he whispered under his breath as he looked at you..he looked like he had been there for a while..you panicked that a human had seen you..
