I knew the prospective romance between childhood friends wouldn't last long without involving an instrusive 3rd wheel who intends to wedge him or herself in between the lead characters. It was fun and going so well with just the two friends trying to help the male lead in his quest to get the female lead to see him as boyfriend material, but it's not going to be as much fun to watch this annoying 3rd wheel trying to dig out some dirt on the female lead.
