I'm trading 10 gems for 20 hearts. If you are interested comment below with your friend code, I'll add you as a friend in my main account and as a referrer in a new one. You can send the hearts to my main by dancing with me or simply sending the hearts daily. After I get all 20 I'll level up the new account until level 11 (just to be sure) and you'll win the 10 gems reward.
