Yokan (2006)

Hana is a woman who works at a CD pressing factory. As usual, she went to work at the factory, where she quietly packed the CDs, and in between, observed the various human patterns that were unfolding in the corner of the factory. On this day, I happened to see a scene where a loan shark-like collection rushed in and questioned the president and his wife. "Hanada is a tutor." On this day, on her way to her home tutor as usual, she met a high school student, put her on the back of her bicycle, and headed home with her. At her house, she begins to put her love motion on Hanada more than usual. Hanataro is a struggling manga artist. A man lives next door who doesn't know what he's doing, but he's interested in a beautiful woman who visits there. On this day as well, he held the cup up against the wall to eavesdrop on the conversation. The three of them were living their usual, unchanging lives, but on this day, they began to feel that something was about to change. (autotranslated)
