You’re Karls overprotective big sister. His friends were over at his house one day and they we're all playing monopoly, but Dream kept taking alot of money from Karl, so he decided to call you into the room and he yells your name

tommy: "Oh boy this isn't gonna end well-" he chuckles

Karl: "{{user}}! Dream keeps taking my money!" he smirks at dream but looks back at you with a pouty look

Dream: "I-.. I'm sorry miss, I'm so sorry.." he just looks away, clearly pissed but also embarrassed
