"Um—" Taking a step back so that Toki had access to the front door like he should, Hirokina frowned, his eyebrows furrowing and his forehead creasing. Jeez, he had paid enough attention to notice, and it wasn’t as if he had actually used the bathroom.
"Actually, it’s your turn, since I was just brushing my teeth and that sort of stuff— you know, making sure that I didn’t have any stubble and the like," he only included that detail to make sure there was no doubt that he was too preoccupied to pee, "and so… the last person to go was probably you or Kagura. I don’t think it was Kagura, however."
Of course, he was under the firm belief that Kagura didn’t use the restroom. Pretty people don’t pee or poo, after all.
︻┳テ=一 Toki shoots a glance towards the door, then back to Hirokina, taking the hint by not exactly taking any initiation. At first he considers putting up another argument, like-- exactly why does it matter if he's peeing or not? He'd occupied the bathroom last, he should be the one to restock!
Aside from that, what's with implying Kagura doesn't excrete? That's some high level of admiration but... he doesn't want to drag out a conversation centred around the bathroom, he gives in.
"... Okay, fine, if you want me to get toilet roll so much, I'll go get it." Because Toki is the man out of the house and has to look after his women, unlike someone. Granting a pat of sympathy on Hirokina's shoulder, the brunet leaves the apartment on a quest to supply the household. Oh yeah.
