Y/N is selectively mute - not because she can't talk, but because of something traumatic in her past that made her stop. She's kind, artistic, and deeply observant. Her world is small by choice. Every day, she goes to a cozy coffee shop in Los Angeles where her longtime friend Toby works. It's her sanctuary. Toby has a lively friend group, including Billie, who's charismatic, guarded, and known for always being the loudest in the room - until she meets Y/N.
