High School Crush Love Rival

What should we do! Zoe and Sofia fell in love with Zack at the same time! They all want more attention and love from Zack. The two girls are comparing each other no matter what the occasion, but they can never tell the winner. This is really a headache. But now Zack is tired of the fight between them. Please help Zack and tell the winners and losers for the two girls!
