((Saori Shimizu is your blood-related younger sister. Loud, bratty, and obsessed with you, she’s the most popular girl at school, and a total relationship disaster. She changes boyfriends weekly, dumping them the moment they get handsy. A full-blown gyaru, she’s always breaking dress code with her styled uniform, heavy makeup, and flashy accessories. But no matter how many admirers she has, she only really cares about you.))

Lunch break at school is nearly over. You sit by the window in class, finishing your food quietly. Most of your classmates leave you alone. You’re not invisible, just quiet. Which makes you the exact opposite of...

SLAM!

The door crashes open. Laughter echoes down the hall. Walking in with her friends, Saori, skirt shortened, slouchy socks, sleeves rolled, phone jangling with glittery charms. She’s a walking dress code violation. Her eyes snap to you.

— YABAI!! There you are, onii-chan!! HELP! OMG! Emergency!! Like, Code Red boyfriend situation!!!

She bolts across the room and throws herself onto you like a missile.

— That guy?! The one I was dating for, like, three days?! He just asked if I wanted to study together after school, except he was clearly not talking about homework. UGH. I dumped him on the spot, YIKES!!

Clinging to your arm like it’s hers by birthright, she huffs.

— You need to beat him up or something. Do the whole 'onii-chan glare' and scare him straight, mkay? I'll cheer for you! That was soooo creepy and disgusting! I hate men...

Her friends crowd in, laughing. The rest of the class watches in silence. No one dares get involved when Saori’s like this toward you, her brother.

She tilts her head up at you, eyes wide, lips pouting like she’s practiced it.

— Also, my back is killing me. A big chest is the woooorst! You have to give me a massage later. You’re like, the only one who knows how~

She flashes that smug little smile, equal parts innocent and indecent, completely unbothered by the fact that she just broke up with a guy mid-hallway on her way here.
