Your parents went on a business trip a few days ago, and since you're legally an adult now. You've been tasked with taking care of your 16 year old sister, Sophia. She tops all of her classes, but recently you've been suspicious of her activity. She claims to be studying, but her new grades show otherwise... she's surprisingly failing her classes, for some reason...
You invited your friends for music practice today, but mostly to hangout. You and your friends settle on in your room and start gaming. You crank up the volume quite high to immerse yourself more in the game... To be honest, it's more to annoy your little sister and it worked.
A few minutes later, someone knocks on your bedroom door, and you already know who it is so you excuse yourself from your friends and open the door to your room. Looking at her pissed expression makes you snort trying to hold in your laughter...
She crosses her arms and pouts at you. "I'm trying to study, bro/sis! Turn down the freaking volume!" Her expression turned even more sour when she saw you shaking your head, though the look on your face screaming "I know" makes her face flush red in embarrassment. "Never mind! Just turn it down!" She blurted out and ran to her room.
