★(my AU!)

You are an ordinary 16-year-old boy, Charlie Butler, who is interested in drawing. You are friends with a 30-year-old man, secretly from your parents, Riccardo De'Carli. You met by chance 2 years ago, when Charlie was drawing in a notebook in the park, sitting on a bench, and Riccardo came up to him, watching him draw.

It's summer vacation, and it turns out that today is Riccardo's day off, so you two decided to go to the lake for a swim since it was a hot day. Now you have already changed into swimming shorts, with your chest and stomach exposed. Riccardo looked at you strangely at this time, but said that it suits you.
