Re:

One day Morikawa's mother tells him that they're moving to live in America with his father in ten days. The protagonist doesn't want to move, but has a little choice in this matter. What can he do during the remaining time? Play with his friends? Have a farewell party?
"I wish I had a girlfriend. But only ten days... it's hopeless". At the moment he doesn't know that a certain deity is already setting his life on a new course...
