3 - The rabbit hutch (cw description of animal death)
A young Orchid and Junpei, both around 12 years old, are taking care of their school's rabbit hutch over the summer. One morning, however, Orchid arrives to find the rabbits have all been killed. She's horrified and upset, of course, but Junpei lifts her spirits by promising to catch the culprits and make sure they don't hurt any of the school's other animals.
The two keep watch over the scene of the crime every day for the rest of the summer, but no one ever shows up. Nonetheless, they enjoy each other's company and take comfort in it.
