Sorry kids, but in the West, "Lemon" means something completely different than "youth," especially in association with parties...
Also everyone's pissed at MC for considering her a "friend," but consider:
He's N E V E R had a friend before her
She's literally the first person who's his friend and that's only recently begun to change, and even still she's the closest one he's ever had. To a relatively normal person like you or I, that may seem underwhelming, but that's probably the closest or most significant of a relationship he's ever had with someone outside of his family. That's a big deal.
Plus I'd argue your romantic partner should ought to be one of the best friend you've ever had, but whatever.
