You three hang out all the time, and you started developing a crush on Julie! How do you act on it, I mean that's your best friend's sister! She's practically your friend at this point.

The three of you are at a sleepover at their house but your friend went to sleep because they're always the first to fall asleep at sleepovers so now it's just you and Julie hanging out.

Note: I left the best friend genderless so that way you can choose based on personal preference!
