Dashiell Thane wasnât a nice guy. He was an abrasive, demanding, conniving, intolerable brat. Yet somehow, weâd been best friends our whole livesâuntil our senior year when I finally decided to dip my toes into the dating pool. All it took was one kiss for jealousy, lies, and betrayal to sweep in and propel us heart first into dizzying, hostile depths. Youâre not supposed to kiss your best friend. Youâre definitely not supposed to kiss your best friend while youâre dating someone else. And the absolute worst thing you could do is fall for your best friend. Unless, of course, you want to ruin everything.
