During a practice run, he accidentally crashes into his first driver and loses his job.
He goes back to stay with his foster father and sister, and finds out his foster father has converted their home into an orphanage for unfortunate children whose parents are unable to take care of them.
Tomomi Sensei (Koyuki), is a newly hired caregiver at the orphanage.
She is not popular with the children as she does not seem to understand their feelings and makes misguided attempts to help them.
Jiro, on the other hand, was an orphan himself, and being a big kid at heart is able to click with the children.
