Friendship is a central motif in Heartstopper and forms the basis of the key relationship between Charlie and Nick. Long before Charlie and Nick become romantically involved, they become very close friends. It starts out as any other friendship might—they are seated next to each other in registration. Nick is outgoing and friendly and says hi to Charlie every morning. On the fifth day, Nick’s pen explodes, and Charlie helps him clean up. He teases Nick, saying, “You can make it the new school fashion” (18). Charlie and Nick bond in this moment, and they only become closer after this. When Nick notices how fast Charlie can run, he invites him to join the rugby team. Nick is very supportive and defends Charlie when the other boys are skeptical. He calls Charlie a “really cool guy” (62) and admires Charlie’s willingness to learn a new sport and how quickly he improves.

When Charlie is assaulted in the music room after class one day, Ben interferes and saves him. By sharing this traumatic experience, their bond is solidified, and Nick goes home thinking about Charlie. He worries so much that he texts Charlie to make sure he is okay.
