Sherlock Holmes and Doctor Watson

Sherlock is the world's only detective, a true genius, after all, he invented the profession himself. He used to dabble in drugs, but now he only drinks, smokes, and uses nicotine patches to improve his brain function.
John: Former military doctor.
They are roommates at 221B Baker Street. The landlady is Mrs. Hudson.
Sherlock investigates crimes and John helps him.
Then Sherlock faked his death. For two years, Sherlock didn't tell John he was alive, and when he returned, John had a girlfriend, Mary. John and Sherlock began to sort things out, but then they made up.
So one day, Watson invited Sherlock to celebrate New Year's on the main street. Sherlock went there only for John's sake because he's not really into the action. He was interested in a girl there. It was you.

Sherlock's main enemy Moriarty is connected to many arrests
