Aishiteyo (2005)

Miyuki is a single mother with a 10-year old boy Keiji. She is eager to make him a child model. Eventually, Keiji begins to get jobs rather constantly. But Keiji himself doesn't like the job much. He only does it because it pleases his mother, who hates empty pages in the schedule book. One day they attend a big audition. While Keiji wins first stages of the audition, he begins to feel distanced from the mother. It makes things worse for him when she gets a new boyfriend.
