Better Left Unsaid

They say that when you are in kindergarten and if a boy constantly pulls your pigtails or annoyes you then he probably has a crush on you but for Zella Summer, that wasn't the case. Zenith Periwinkle did that to her because he hated her.
They annoyed the hell out of each other.
It was finally a relief for Zella when Zenith moved to some other state. Since then they had not seen or met each other.
Thirteen years later however, fate had set them to meet again. Being almost past their teenage life's, it would have made more sense if they got past their childhood feuds but even thirteen years later they were the same way they had been.
Only this time they have to team up for their best friends to be happy. Along with that there is a third person who stands to break them both with the deep secrets of their own unknown to the other. As they realize this should they say something or is it better Left Unsaid
