Headscratchers / Pinkalicious & Peterrific

• In Cupid Calls it Quits, when Cupid cancels Valentine’s Day, love literally disappears from Pinkville. As a result of that, Pinkalicious’ friends now nonstop argue. However, Pinkalicious still retains memories of their friendship, and her and Peter’s relationship didn’t disappear, either. So, how exactly did Cupid’s love-removal thingy work?
• In the same episode, why not ask Cupid to wait a day or two before he starts living like a normal kid? Or does he work year-round for some reason? Cupid's actual involvement in Valentine's Day is confusing because, unlike Santa, he doesn't make the Valentines; he seems to deliver them, but you would think that most people would just give their Valentines to people or send it through the regular mail if Cupid wasn't available. Does he have some kind of exclusivity contract?
