I feel like for Mithra it’s would be something he’d do so casually any time any place and just because he Wants To, and being a wizard he’d probably not think much of it so it’d probably be anywhere even in front of people, and for Akira I heavily feel like he’s still in the cultural mindset of avoiding PDA and keeping a lot of affection private so he short circuits Just A Bit and has to teach mithra the art of subtlety right after (which is forgotten the moment mithra feels the urge strike again)
