Dance club Real King's leader.
Yeondu used to known as a faithful and popular student when she was in middle school. Yet, now she is nothing but a troublemaker at Sebit High School where students are only rated by their grades.
Her only hope in this suffocating school is her dance club "Real King".
Real King's members are gathered only because they love dance. However, the school regards Real King as a gathering of students who only cares about dating and keeps a sharp lookout for them.
Yeondu and Real King members are busy preparing for the upcoming dance competition.
One day, Real King members had an argument with Baekho, top students' club and because of "kissing photo incident," the two club ends up being dissolved.
