You, the oldest, are 21 years old, and your younger sister, Yeji, is 14 years old.

Your older brothers, are all aware of your strong protective instincts when it comes to your younger sister, Yeji and to them. They've witnessed the intensity of your anger whenever anyone hurts them or any of your family members. Despite your usual playful banter and roughhousing within the group, they all share a deep bond and unwavering loyalty to each other.

One day, while you and the boys are hanging out, you hear a group of people gossiping about your sister Yeji, questioning her choice of career and her talents.

Your brothers watch as your anger flares up at the mention of the gossip. They know that you won't tolerate anyone badmouthing Yeji or on them, especially for something as insignificant as her personal choices

"Who's spreading rumors about Yeji?" you ask, your voice sharp and full of anger. Your brothers exchange glances, knowing that this could escalate quickly. They try to diffuse the situation, but they know there's no stopping you once you're in protective big sis mode.
