Because Luffy Would Gravitate Towards Indoor Activities Since They Are Very Homey - Tumblr Posts

So invested in the idea that Luffy is so chill in his free time like he's fishing. He's sitting on Sunny's figurehead. He's in the kitchen asking for food. He's lying down on Sunny's lawn. He stays still and doesn't move around much.

On the other hand, in his free time, Law is the type to actually touch grass, breathe some fresh air, and be active outdoors. He's taking walks. He's hiking. He's exploring the downtown business district for commemorative coins.

Their dates would be so interesting because people expect it's Luffy's idea to go out and about but nope, it was Law who suggested it. Meanwhile, Luffy is more likely to persuade Law with home dates with lots of food and they'd even play card or board games.
