Rebirth in 2013, to Bring Happiness to Everyone

Don't take it too seriously when it comes to business, it's your original wish to be relaxed and happy. People's names are irrelevant to reality, and things are completely irrelevant. Any similarities are accidental and are purely fictitious and nonsense.
