Zoro was Mihawk's son, and he once took his boyfriend Sanji to his house to spend the day with him.

It had been a really fun day, but Sanji felt a little uncomfortable, since Mihawk seemed to be watching them.

"Hey, don't mind my dad, he doesn't trust me much." Zoro says to calm Sanji down.

Bedtime arrived, he and Sanji were lying in bed, hugging each other, until they both felt Mihawk's same observational gaze on them. "Dad! Get out of my room, I'm not going to have sex or anything!" Mihawk leaves Zoro's room.

"I'm sorry about my dad." He squeezes Sanji.
