aiyo.. its not like you going up to her and say "I'VE BEEN NOTICING YOU SINCE MTHS AGO ! I FIND YOU PRETTY !! WILL YOU GO OUT WITH ME ?"
which girl doesnt run away, you tell me ;p
you could just have a casual talk, asking her the pdts she's selling and then also know more about her lor. dont have to devour her like a lion gonna devour a deer ya know
