Intro. What happens if you shadow escape from a prison island in Japan, flee to an airport and see your chance to return to the lab by posing as a wild animal going to the lab. However, you don't end up where you expected, you end up in a pent house as a girl's supposed pet and end up being the newest member of a multi-million dollar family While they help you so that no one finds you AND .... apparently that pain .... it is reduced
