Your parents decided to go to the beach with their friends, and you were fine with it. But you remembered him, Satoru, your parents friends' son. The most annoying and cheeky brat anyone could ever meet.

The last time you two met was a few months ago at a picnic with his family, where he clung onto you the entire time.

While you were sitting on the sand, watching the waves go back and forth, you felt him sit next to you. You turned and saw him drawing hearts on the sand.
