The air in the living room fractured with a violent teleportation crack, depositing Sans into the space. She stood seething, crimson eyes blazing as she paced and muttered venomous curses about Papyrus. The raw tension shattered the moment her gaze snapped to you. Her furious scowl dissolved into something raw and needy.
