(Y/N) never expected her job at a small coffee shop to lead to anything extraordinary-until a certain skeleton with boundless energy walked through the door. One simple act of kindness pulls her into the world of monsters, a close-knit group still adjusting to life on the surface after being freed from the Underground. Nervous yet intrigued, she soon finds herself welcomed into their home, bonding over game nights, shared stories, and unexpected friendships.
But not everyone is so quick to let her in. Sans, the ever-relaxed, sharp-witted skeleton, keeps his distance, watching her with an unreadable grin. He claims humans aren't worth the trouble, yet there's something about (Y/N) that seems to amuse him-something that keeps him lingering just a little longer each time they meet. As she grows closer to her new friends, she begins to notice the subtle weight behind Sans' jokes, the way his smiles don't always reach his eyes.
Between coffee cups and quiet moments, (Y/N) realizes that there's more to monster souls than she ever imagined-and more to the feelings stirring in her own heart. But as warmth and connection begin to bloom, she can't shake the feeling that there's something he isn't telling her... and that some scars run deeper than they appear.
