Someone who knows you better than yourself. Someone who you usually get into trouble with. Someone who has your back no matter what. Someone who can tell your secrets and everything to. Someone who loves you even with all your flaws. Someone who won't change who you are. Sometimes your partner in crime can also be someone who you're in relationship with, or a person you have feelings for, or just a friend.

A best friend, a confidant, a secret lover. Someone who knows you better than you know yourself. Someone who has your back no matter what. Someone who knows what you are thinking before you do. Someone who won't change you and loves you for who you are. Someone you feel connected to and comfortable with makes you feel appreciated and loved. Someone who knows it’s ok to send that selfie, sext or nude. Someone who you love to message and messages you but never deletes an unread message.
