You play a young man which dies on in a motorcycle accident, becomes a ghost and goes to heaven where he meets up with Ai, the Japanese Teenage Angel of Love, who who tells him that he can be brought back to life if he finds true love within six day.
When the ghost is sent back to earth he sees a girl, Rina, sitting by the seashore....

Death has made you invisible and gave you telekinetic powers.
Interaction is handled by two or three-choice dialogue trees that pop up in the midst of a conversation.
You typically communicate by scribbling kanji in the sand, on chalkboards, or on the screen of Rina's iMac.
Certain phrases will boost the Love-O-Meter", while others will make you look like a total bastard.

The Love-O-Meter" is at the bottom corner of the screen, which shows off the amount of affection Rina has for you.
Your goal is to help Rina with her personal relationships, and save her from any harm.

0Story is pronounced as "Love Story"

This game is completely in Japanese.

Apparently half the game is shot on film, and half on video, they probably ran out of funds and had to rely on consumer-level DV cameras.
