The Special Tutor.

Satoshi, who lives in a wheelchair, accidentally captures the moment his tutor, Haruka, falls while taking pictures of the scenery from the balcony. Meanwhile, Satoshi's father is attracted to the beautiful Haruka and asks her to give lessons to Satoshi with ulterior motives. When Haruka comes to the house, she asks Satoshi to show her the photos from that day, and they begin an intensive private lesson.
