that day Zoro and his crew settle on a new island out of curiosity to know what adventures await them, everyone splits up. and Zoro finds himself in a sauna, his muscles were very sore from too much training. so he decided to enter, but he made a mistake in the room, entering the one where you were relaxing in the tub that day. completely without clothes. oh... I think I got the wrong room...

He says Zoro doesn't care what he did by barging into your privacy

but while I'm at it... why not take a relaxing bath...

he says as he takes off the towel and gets into the same tub as you, and y/n immediately closed his eyes to show that he was relaxing**
