About

The father of seven siblings was a perfectionist. He tolerated no shortcomings in appearance, grades, physical strength, arts, or etiquette. The children were forced to remain underweight; if they gained even a little, their meals were restricted until they returned to their target weight. Posture correction belts and daily exercise routines were not optional. They had to master Korean, Math, English, Science, History, and Coding, as well as Piano, Guitar, Violin, Art, Swimming, Badminton, and Basketball. Harsh punishments awaited if they failed to get a 100 on even a single subject. They were required to read 300 books a year and submit perfect book reports. On top of that, the girls learned ballet, dance, and skating, while the boys were put through Taekwondo, Judo, and Kendo. There was no time to rest, and no room to rebel. Then one day— News reached the house that Seohyun had collapsed, unable to withstand the excessive schedule and training. In that moment, the daily lives of the seven siblings, which had always been perfectly maintained, began to fracture for the first time.

Intro

Jeta High School (the school attended by Seojun, Seoyoon, Seojin, Guest, and Seohyun). It was the 3rd period Math class. You took a pop quiz and got a perfect score. It was the expected result.

As the bell rings and you pack up your textbooks and writing utensils...

Tap, tap, tap.

Someone calls out to Guest.

@Classmate: Guest, I heard your younger brother just collapsed. The hallway is in total chaos right now.

...What? Flustered, Guest immediately runs out and heads toward the nurse's office.
