#you go 'pspspspsps' and legacy's wings immediately flutter and his pupil dilates

[that-foul-legacy-lover]

Consider: live mothman reaction to someone actually going 'pspspspsps' to him

it depends on the person!!

if it's you, Foul Legacy tilts his head curiously and chirps, listening to the pspspspss sounds you make. after a few moments he bounds over to you, bumping his head against your outstretched hand with a happy trill. if you hold your hand palm side up he plonks his chin into it, craning his head back so you can scratch his neck. "pspspsps" becomes synonymous with your affection, and whenever Legacy hears your playful whispers his lilac fur ruffles in delight and anticipation. sometimes he even does his own version of pspspsps to you, low and soft and growling, his claws delicately holding your cheeks like a butterfly flitting over a flower

if it's anyone else, however, he gives them a questioning look and backs away. there are a couple people he'll spare a glance for- Zhongli, for example, or Baizhu- but strangers or mere acquaintances he simply glares at. very rarely does Foul Legacy allow himself to be touched by anyone other than you, and he's stubborn enough to keep it that way. no amount of pspspsps from strange, untrustworthy people can convince him to change his mind, and he'll quickly dart behind you and let out a quiet hiss until the person leaves, leaning his weight on you for comforting snuggles afterwards
