Nothing much happens when it's your first year as a junior in a sorority group, but what happens when senior year comes?        
Meet Lee KyungRin.

She's a senior and a member of the sorority group 'FERRARI'. She expected her second year in FERRARI as another ordinary year. Well, she thought wrong. What happens when something called 'love' comes in the picture and there is a mess in the FERRARI family? Will she be able to be happy and graduate senior year?    

Maybe not... When she meets Shin Peniel.
