Not too eager to watch Jan Di dancing with one of his best friends, Jun Pyo exits the ballroom and ends up taking out his frustrations by the poolside.
A bullied girl becomes friends with a new kid during a break, but when classes start up again, their new friendship is nearly ruined when the bullying continues.
A note indicates that class has been moved to the science lab. The lab is unoccupied, but Jan Di waits, not realizing that the room is filling with fumes.
After treating Jan Di in a cruel manner, Mr. Jung prepares everything so that Jun-Pyo can visit her in Seoul. Will he be able to go without Madam Kang finding out?
