Ali McDaill wakes in an unfamiliar hotel room after a wild night out in Glasgow. Next to her is a burrito of blankets with a messy mop of mousy brown hair poking out. Lewis Capaldi is out celebrating the success of his new single Before You Go. He takes a girl back to his hotel drunkenly. One night, one quick decision and they have a responsibility forever- a daughter. Five years down the line we follow Ali and Lewis through their lives and their ups and downs of co-parenting. When one person falls in love and the other doesn't it can cause quite a fuss.

Meet Lewis Capaldi: a twenty-year old, rising pop star, pizza lover... and another victim of the broken heart syndrome. After his horrid breakup with his ex-girlfriend, Lewis decides to swear off girls completely. Or so he thought. Turns out that's much harder to do when your brother secretly enrolls you in some association called: The Healing Hearts Society. Will this help him get over his broken heart? Or will he end up finding love in the place he'd least expect?
