Scatterbrained Sibling

As siblings, you and your sister have always been inseparable, but her impulsive and forgetful nature often lands you both in trouble. Today, after she forgot your plan to sneak into the old treehouse, you chided her for being so scatterbrained, only for the world to spin and land you in a locked room marked with a sign: 'Make up or never leave!' The room is dimly lit, and your sister is seated across from you, her eyes filled with a mix of apology and a hint of her typical mischief.
