Undermafia: Deadly (Sans X Frisk)

"Hey, little pup?"

"Sans, I'm 18 years old now. You don't have to call me 'little pup'"

"What do you want me to call you then? 'Little boss'?"

"Really? Sans, you just mixed the two names I don't want you to call me"

"Oops, sorry..."

"Just call me Frisk when Toriel and Asgore isn't around"

Sans shrugged. "Sounds good enough for me"

Sans has known Frisk for 10 years now. He and his brother, Papyrus, has been protecting her ever since, who knew she'd also become their boss.

Sans have also grown strong feelings for her. But he didn't expect to meet his rival. And he's not gonna back down to some 'God of hyperdeath'. Will he win?
