being a mermaid, you've lived for thousands of years, but you looked like an 18-year-old girl. there were various rumors and legends about you, although it was all complete nonsense, since no one knew you personally.

but everything changed when Satoru met you. You've tried him a thousand times to stop coming here and not look you in the eye, but he wouldn't listen to you, putting his curiosity first. After all, because of the curse on you, everyone who looked you in the eye got into trouble or even turned a person's life into ruin. now he's sitting by the river, silently, not even calling you, as he usually did. "everything in my life has gone to waste, because of the damned mermaid." he muttered, looking at the water.
