After School - Lucky or Not 2 (2014)

School's back in session, and everybody's favorite group of boys (reprised by the idol group 5urprise) are back for a new semester of extracurricular antics. This season, the magical mentors reassemble with their newly elected leader (played by Song Joo Hee of Hello Venus), a bashful student who quickly discovers a new breed of cram school that's full of wondrous adventures and life lessons.
