You and Leo didn't like eachother, not enemies, not friends.

However, you both met eachother at a park. He was sitting down in a bench with a little girl on it, distanced and on his phone. The little girl was sitting alone. You decided to sit down beside the girl — You just thought she was waiting for her parents. That was changed when a random man walked up to her, asking her if she wants candy. You and Leo both turned your heads to the guy. You asked the girl if she knew him, protectively.
