Item Box Farming Method

As the title says. My own efficient method for farming item boxes. I'll be using the 'Romance Blooming Academy' scenario. First, I rest until the second week of March. This maxes out 'Heart Fruit' at 58. Then, I play blooming matches against B-rank high schools. After 6 matches, the 'Heart Fruit' runs out, so I rest again. When I have about 15 'Heart Fruit', I play 2 more blooming matches. After that, I just keep resting until I become the first draft pick. It takes about 10 minutes. This is probably the easiest method.
