Did the joke fly over me or did he just imply he's got a smol pp or something? 😭

Basically the antler is a good cure for those who can't get it up, mc thought ml needed it but he turned the table right back at him lololol

Ah thanks ejfnejwk that legit got me rereading the last few panels huhu (is really slow and bad with picking up innuendos )

My guess it that while it is a "sexual stimulant", it's also good for stamina in some sort of medicine. ML is too upright to make joke like that. :P
