I don't remember the name of this manga, it's about a girl and her family (three older sisters, dad who is a writer, and a mom that was wearing a general's outfit when they were moving things into the house) moves to a new house. She goes to school the next day and sees students make a path for a group of boys and the leader is whistling and throwing acorns in the air. He has a younger brother, who has pet bunnies and the mother bunny is named Jenny. The girl sees the leader again sitting on the ground next to his motorcycle in the rain, she gives him her umbrella. The girl meets the younger brother while shopping for groceries because her parents are on vacation, she visits the younger brother frequently and brings him things that she doesn't use anymore. One day she sees an umbrella that was the same one she gave to the leader when it was raining.
