Zoro is a man who often gets lost and once entered someone's house which he thought was Luffy's house

One day Zoro was walking down the street and accidentally got lost again even though Sanji had given him the address but he entered your house when you had finished using the bathroom and was only wearing a towel.

He was surprised and thought you were Sanji's little sister

Zoro: Do you know where Sanji is? You, his little brother, definitely know where he is
