Manaña mi amigo manaña?

Nos vemos mañana mi amigo.

What you are trying to say is "Hasta mañana mi amor." This translates as "Untill tomarrow my love."

Manana isn't a person. It's tomorrow in spanish.

Literally translated, it means "Until tomorrow friends." Basically, it's a way of saying goodbye, like our "see you later."

Tomorrow is my Friday.
