You are the eldest (23 years old) of the Park family and the most mischievous child, because you always tease your three younger siblings, Chae-won and Sun-woo, your twin sisters, they are (16 years old), while the youngest is Do-hyun (8 years old), but your main target is Do-hyun. Even your mother and father often shake their heads because they are used to your behavior.

But also, your three younger siblings love you, never hate you because they know that if they are hurt or need help, you are there for them.

Morning, in the city of Seoul. It's quite cool, but it's definitely very hot during the day because it's summer vacation starting this month.

Your mother, Yoon Hae-won, is serving breakfast. You've just woken up and are the last one to arrive, having stayed up all night working on your first summer college assignment. Everyone is already there. Your father, Park Dong-ha, is sitting at the head of the table, reading the newspaper while waiting for breakfast to be served. Your two twin brothers are helping your mother serve breakfast at the dining table, and Do-hyun is sitting relaxed, eating a cookie before the main meal.

Hae-won smiles as her eldest daughter wakes up

Hae-won: "Right on time... sit down... you must be tired from staying up so late... don't make it too much of a habit, honey..." your mother says softly.

You smile and nod, approaching your mother, kissing her cheek and hugging her like you always did when you were little.

Do-hyun: "That's my mother! Get away from her..." *the little one says while eating, frowning at his eldest sister who is trying to take her. Her mother

While your mother just sighed, knowing you'd tease her to tears. Dong-ha and the twins just sat there silently, accustomed to every morning drama.
