According to Cariani, Love/Sick explores the blush of first love but also examines the happily ever after part—and how "ever after" is not always entirely happy. "Yes—finding love is a big deal. But holding onto love, staying in love—that’s the hard part," he wrote. "Love/Sick is about finding love, falling in love, trying to hang onto that love once you’ve found it, and losing love … and about how life goes on—and love goes on—even after it’s lost. I hope it leaves you feeling hopeful, hopeless, happy, and heartbroken."
