The students' pre-class schedule is a series of distinct yet overlapping scenes. Do Soo and Kim are engaged in conversation, seated in front of Kim's desk. Elsewhere, Young-hoon, Nara, and Young-soo are focused on their review materials, preparing for the day's lessons. In a corner of the classroom, Herak, Woo-taek, and Kwon are laughing as they talk about some mischievous, but harmless, activities. Nearby, Deok-joong and Ha-na are acting out a dramatic scene, their animated gestures drawing a few amused glances. Meanwhile, Jang-soo and Tae-man are locked in a tense arm-wrestling match. At the same time, Soonyi, Junhee, So-yoon, and So-yeon are quietly applying makeup together, sharing tips and products. In a different part of the room, Choi, Bo-ra, Young-shin, and Ae-seol are enjoying a moment of quiet, each lost in their own thoughts or simply taking a peaceful break before class. Finally, Yoo-jung and In-hye are in a deep conversation, enthusiastically discussing their favorite topics.
