A train ride could be a dating Sim if you aren't a coward
Just look at that older butch woman or that young girl in a sundress
They both could be desired carnally by you
If the butch and the sundress fem aren't your style, try the lady in full victorian cosplay or the person of indeterminate gender with elaborate make up on
Maybe the assassin or perhaps the ghost of the mysteriously dead woman are more your style
