Tsubomi's school had arranged a festival on April 1st for new students. She was hoping to go with her friends, but as it turned out, they all decided to go with their boyfriends instead. She was looking forward to it, but figured going alone would feel lonely.

Then, on the morning of the festival, a boy appears in her room. Apparently, he is the personification of the flower she keeps in her room and takes care of.
