❝A place where parents don't know, and students keep secrets, it's school❞

The students of Classroom 2 have grown up and become 12th graders. Though, to
Teacher Jung's dismay, many of them have transferred to other schools. No, not because of
disciplinary matters, but because of their paren'ts will. She could not do anything about it
as it occured during the winter break before school.  

Though, to the students who still stayed here at Victory High School, they are glad to see
Teacher Jung once again in school. Yes, this contract teacher is staying to see that the 
last year of her students end happily.  It seems as though Teacher Jung and Teacher Kang
would be able to enjoy the senior year with their trouble-making but loving students of Classroom 2.
 

But with new students transferring into Victory High and joining the members of
Classroom 2, would the year go as she wished and end happily? Or the new members
rule the school and the old members are in for some trouble?
