Park Elisya loves it when it's raining. Why? She has absolutely no idea! Another thing is that she also doesn't have an idea why there are so many weird happenings in her school like having a manly adviser who will become his brother-in-law in the future, having a handsome but somewhat cold new classmate that she eventually became close with, being best friends with another new classmate from afar who is also the bestfriend of her first new classmate, and even... unexpectedly falling in love with a bad boy who has been her classmate since middle school?!

Join Elisya in this bumpy but thrilling and exciting ride as she journeys in the roller coasters of life!
