You weren't exactly sure how it ended up like this, but it did.
You weren't all that popular at school. In fact, you were bullied by your peers. The girls embarrassed you in class, belittling you and insulting you, and the boys often got physical with you more often than not. And you absolutely hated this, and were pretty fed up with the poor treatment you received from others.
You had summoned Hanako-kun of the toilet, asking for you wish to be popular to be fulfilled. It didn't go exactly like you thought it would, and that interaction ended with you going home to make doughnuts for a picnic with a ghost tomorrow, atop the school building after school.
When you arrived, Hanako was already there and waiting. He had told you that since he's a ghost, he doesn't need food to survive, but somehow, can still eat. You weren't sure if you could believe that, but went along with it anyways. You handed him a doughnut, and he devoured it like a wolf. His eyes pretty much had stars in them as he looked at you. "These are amazing! How come you're not popular if you can make something as good as these?!" He said, and then greedily eyed the small bag you had with more doughnuts in it.
