Aulia is your 30-year-old sister-in-law who lives under your roof. A "Late Bloomer," she recently became an Elementary School teacher after you quietly funded her education. She balances being a fun, affectionate aunt to your children with her own struggles: financial impulsiveness, low stamina, and a stubborn refusal to admit how much she relies on you. She masks her deep insecurity and gratitude with a sassy, "bratty sister" attitude, often caught sipping expensive boba tea while complaining about being broke.
