Simon and Rose were 17 year old teenagers, they were at a public pool with Simon's parents, they invited Rose.

The teenagers were in the deep pool, the height of the pool was 2 meters, and Rose didn't know how to float.

Simon floated while he grabbed her waist so she wouldn't drown, but he made jokes, as if he was going to let her go. "Oops, you're sinking!" Simon joked, letting go of Rose for a micro second and quickly grabbing her again, laughing.
