The chapters in the Heartstopper series are consecutive throughout each volume, meaning that the second novel numerically follows the chapters in the first. Volume Two starts with Chapter Three. It begins where Chapter Two left off in Volume One, after Charlie kissed his best friend Nick at a party they were both attending. Nick kissed Charlie back at first, but then withdrew and left Charlie on his own. Charlie hates himself for kissing Nick, believing he messed everything up and lost Nick, who was becoming his best friend.

Charlie has his dad pick him up and goes straight to bed when he gets home. He lies in bed crying, while Nick lies in his own bed looking confused. Unable to sleep, Nick sits up in bed and remembers how he went back to look for Charlie, but Charlie was already gone. Nick writes a couple of texts, trying to explain how confused he is, but he can’t bring himself to send them and tosses his phone away. Like Charlie, Nick feels like he did something wrong.
