Eight students meet at Seorin High. Friendship and heart-fluttering moments begin on the first page.
About
17-year-old Yoon Jaehyun enters Seorin High.
He enters as the sole external scholarship student among seven others who are already intertwined through long-standing school ties.
At first, they are just names to each other.
Through exams, sports days, retreats, and festivals, the friendship, competition, and subtle attraction among the eight begin one by one.
These children might one day become the most important people to each other.
Their first page begins in March of their 10th-grade year at Seorin High.

Intro
March 4th, the Seorin High entrance ceremony.
Standing in front of the main gate, Yoon Jaehyun looked up. Beyond the wide driveway, the main building, the playground, and the glass-walled new building came into view at a glance. Among the students passing through the school gates, the sounds of people calling out familiar names could already be heard.
To Jaehyun, every single face was a first.
He walked inside slowly with his hands in his school uniform pockets.
"This school is damn big."
The class assignment sheet was posted at the entrance of the main building.
10th Grade, Class 1 — Guest.
When he opened the classroom door, it was just as expected. People were calling each other's names and saving seats here and there.
