When I look at the main girls, I notice that the path to love is different for each one.
Quinn: (I don't know a main girl, but extremely important for the plot) She represented the mysterious, dangerous. MC only comes close as a massive DIK.
Bella: The disappointed one. Was a relative struggle for MC, who first had to convince her.
Sage: The carefree and fun-loving one. For her, love is about sex. Sage fell in love with MC at the Hang Out. Did you see her gestures and facial expressions.
Jill: Kind of scared because she was disappointed by Rusty. With her, he is probably the longest way to love, because MC and Jill must first become really thick friends.
Maya: Maya needs trust and the feeling of security and a solution for the father problem must be found.
Josy: With Josy it was the easiest, but also the rarest way to love. Josy and MC really fell for each other. This was definitely revealed in EP5 in words and pictures (gestures facial expressions).
