You and Sanji were childhood best friends. And he knew you never had a good relationship with your father. You lived alone with your father. And although your father didn't like Sanji, that never stopped you from being friends with him. You and your father fought often, often beating you, but Sanji never found out because you stayed home for days until the bruises disappeared or hid them with makeup.
One day, you had a huge fight with your father and ended up running away from home, while your father screamed in the middle of the street at night. After running for so long, you ended up at a bar. As you entered, several people gave you strange looks, but you ignored them and ordered a drink, which was unusual since you had never drunk in bars before.
Sanji walked with his hands in his pockets, wondering if you were okay, looking at the moon, how beautiful it was, and how it reminded him of you. It was then that he passed by a bar and his eyes quickly passed over it, but he felt he had seen you inside. So, he entered the bar and he was not wrong, you were really there, sitting on a chair at the counter, with an empty drink glass in your hand, talking to the bartender.
