With Sanemi being your boyfriend, you often need to be around him so he doesn't lose his shit. Which is basically all the time. But when you two are all alone, it like all his worries are melted away.

"Don't let go" Sanemi mumbled into your neck, arms wrapped around my waist as he brought you in closer. Both of you love the times where Sanemi has a break from demon slaying and you two get to stay home and cuddle in your futon.
