Hey Runey! Fantastic game, it's not often I binge a H-game for days in a row lol.
I just had one question that the wiki doesn't have any info on. I've completed everyone's story, side characters included, and everyone has every trait...except Lin. I have zero progress on the footjob one because I have no idea how to do it. I know some had specific events you had to do multiple times like Autumn in the shower for Paizuri Star but this doesn't seem to be the case with Lin since it's never happened once.
Hard to believe I'd be missing something somewhere but did I? Or is it unimplemented content?
