Because @skylrks said it and I went: absolutely doing it immediately
According to Haru-logic, as long as Haru didn’t crowd, she could be on Namimori grounds. It wouldn’t make sense to say she was never allowed on because she’s visited for a Gymnastics meet before. Yes, Haru is on the gymnastics team, and she’s pretty good at it, thank you very much.
Alone, she made her way up to the rooftop somehow with the intent of using the higher ground to look for people. Instead, Haru in her avid love for cute things, got distracted. In a nest, she saw a small group of sleeping yellow birds. They were so small-- were they babies? Perhaps the parents are away looking for food to feed these babies?
Look at how cute they are! Haru couldn’t help but mentally coo at the sleeping featherballs of cuteness. As a professional babysitter, Haru would watch over these birds until the parents came back for them. Getting to watch these cute birds sleep was payment enough.
