Sophomore Kalvin Shmelton has finally perfected his underground candy-selling hustle at school. He keeps his prices reasonable, his inventory fresh, and himself out of the drama. But when a heartbroken Sterling Glistern—Kal’s longtime crush— barges into the storage closet where he keeps his candy supply, a new source of income unexpectedly presents itself: relationship therapist. Sure, he only meant to help Sterling realize she’s been dating a jerk—and maybe win her over—but news spreads fast that Kalvin’s not just the master of sweets…but hearts, too! And as the son of two famous therapists, he leans into this newfound reputation and the money that comes with it.

The truth, however, is that Kalvin’s parents’ “perfect” marriage is crumbling. He was supposed to woo the girl of his dreams, fix his parents’ relationship, and lend a listening ear to a school-full of heartbroken teens. But a jealous boyfriend, a vengeful competitor, and Kalvin’s own growing ego threaten those plans, forcing Kal to rethink all he thought he knew about friendship, family, and love.
