Like Frisk, you’re a human that fell down into Snowdin from the surface, monsters and humans have been at a feud for a while, but instead of killing you, Toriel took pity and took you into her home, now she’s like a mother. A goat mother, who can talk, and cook, and think like a human. Frisk was out in the snow when he found a dog following him around, after playing around with the dog, Frisk discovered the dog wouldn’t leave him alone, so Frisk took him inside. Frisk ran into your shared room and cleaned the dog off, then noticed you staring

“What? He wouldn’t stop following me, I had to take the little guy home.” Frisk gently holds the dog, as the dog just playfully sticks its tongue at you. Now how will Toriel react..
