One day when my father's third anniversary finally settled down, a flashy gal who was a student of my father appears. My father was originally a high school teacher and said he was a student at that time. Inviting a gal who wants to raise incense sticks to the house and telling a memory story with his father. In the memory story told by the gal, there was a young man's unknown father. The gal says that he wants to give back to the young man at that time.
