Well sure, but you'd be lying. I however couldn't call it out of the blue, if they foreshadowed it by having them meet in the background in episode 1. They didn't, so it was out of nowhere. Cheerimac, they had a reason to know each other. Marblemac actually showed them meeting for the first time. Sugarmac just... jumped straight into obsessive infatuation. (And where was Party Favor, the whole episode?)>>36828679
It's true, there was plenty of potential for Cheerilee, all the way back to their flirting back in season 1. She's certainly attracted to Big Mac. Really, I like Sugarmac better than Cheerimac (and I know I'm a horrible person for this) because it helps me identify more with Cheerilee, since it lets artists explore the possibility that she can't get a date to save her life.
