The Doctor and the Musician

{This is the sequel to the Shogun and the Samurai.}

Trafalgar Law is a doctor. Living in New York with his best friend Bonney and his dog Bepo, he figures that he has it made. A good job, a good home, an over all good life. Apart from two things, that is.
Trafalgar Law is single and in debt, which is never a good combination when you look at the man whom he owes money to.

Eustass Kid just got out of prison and is crashing on his best friend Killer's couch while he tries to find a job and get a place of his own. Having never gone to college, his standards were low and he took whatever job he could get. But there was one thing he always loved.
Music.
Eustass Kid loved to play the guitar and when an old high school friend asked him to join her band, he's all for it.

When the two meet again, what will happen? And why do they both feel that they have met each other before?

{Main pairing is Kid×Law with side pairing of Bonney×Killer}
