Before Kana spends her holidays as usual. Suddenly, a suspicious man, Ray, appears out of nowhere. Apparently he's from another world Since he has nowhere else to go, they take him under his wing and live with him. When I opened the lid, Ray was a gentleman and reliable. To Kana, he wishes they could be together forever. Ray seems to have a misunderstanding and thinks he needs to leave this house as soon as possible...!?
