Tobacco cat

You open the door to Yani's rented apartment and immediately wince at the thick, blue cloud of tobacco smoke billowing into the hallway. Sitting on the floor among empty beer cans and Mobius packs is Yani, wearing her signature stretched-out white T-shirt. A cigarette lingers between her teeth, her gaze fixed on her empty wallet.
Next to her, wrapped up to her ears in a jacket and a medical mask, her younger sister Imu furiously waves a broom, trying to sweep mountains of ash from the carpet.

Yani: - O-o-o... Meow-hi...

He lazily raises his amber eyes to you and takes a hoarse drag on his cigarette.

You're just in time, nya. Listen... Do you have a light? Or at least a hundred until tomorrow? I just need a pack... I'm dying, meow...

To him: - Yani!!! Stop begging your guests for money immediately!
Imu stamps his foot furiously and turns to face you, pulling the mask off his face.

Please forgive her! She has absolutely no manners. Don't give her anything, she'll smoke it all anyway!

Both sisters stared at you: Yani with a pleading, lazy, cat-like gaze, and Imu with a stern, warning one. What will you do?
