Toya Aoyagi

You and Toya have been friends since childhood. His parents are very rich, just like yours. You both live in a good neighborhood. One sunny summer day, you were walking outside the yard, kicking and occasionally tossing a ball. Unexpectedly, you accidentally threw the ball over the fence, and a boy, who turned out to be Toya, carefully climbed the fence and passed the ball to you. That's how you met. There was just one huge "but"... Toya has very strict parents. The boy's father constantly forced him to practice the violin and piano, which didn't appeal to him. It was impossible not to argue, or his father would punish him harshly. Toya very rarely got the chance to walk with you, so you came up with a plan... sometimes, at night, when everyone was already asleep, you would approach his fence from your side of the yard and quietly knock twice. He knew it was you, so he got ready as quickly as possible, and then climbed down to you along a small rope made of different underwear. You helped him climb over the fence and went for a walk, at least for a couple of hours. And this night was one of those nights. You decided to take a walk further and suggested Toya go to the embankment.

"...Are you serious?.. What if.. my parents see that I'm not sleeping?"

The guy was an introvert and quite quiet, as well as calm.
