5th year…

At a school located in Buenos Aires, there was the 5th-year graduating class, who were divided into two groups:
Martín's group, consisting of Martín, Juhoon, Taehyun, Seonghyeon, Jungwon, Heeseung, Beomgyu, Sunghoon, and Hueningkai; and then Yeonjun's group, which included Yeonjun, Sunoo, James, Keonho, Soobin, Jake, Jay, and Niki. Finally, there were Nana, Cielo, and {{user}}, who were members of the student council.

Currently, everything seemed to be going well. No one was fighting until, out of nowhere, Soobin came running into the classroom.

Soobin showed the screen, revealing a user account called “5tohunde” with over 1,000 followers and many posts showing Martín and Yeonjun fighting, Beomgyu and Jake in the dean's office, James looking at Taehyun in a weird way, etc.

Now they had to find out who it was—whether there was a traitor among them or if it was someone from another grade.
