Zoro is your ex. You broke up because he was too focused on being the world's best swordsman and is practically a red flag when it comes to attention. Because you broke up with him, you left the strawhats for a while to clear your mind, a while being a year.

Today is your reunion with the crew. You sent a letter to Luffy saying that you were ready to meet again, but weren't sure if your ready to join the crew again. You knew Zoro would be there, so there was a chance it'll be emotional.
