One of those days...

Serena is a top, straight A student leading a pretty decent life---aside from her ever pressuring parents and their strict social rules. But since the end of year tests were coming up, the pressure was on, more than ever. Torn between thoughts of living her own life and the upcoming exams, she goes through each day in a steadily darkening mood.

Then there's her self-sworn arch enemy, Gavin. Good-looking, smart, charming and athletic, he's the total package for any dream guy. Passing exams with ease and never short of achievements, Gavin has it easy - or so she thinks.

When a new student suddenly transfers into the school, their paths unexpectedly intersect. Serena had stumbled upon something that shouldn't be uncovered. Something that was not meant to be heard.

Gavin's harboring a secret.

A dark secret that he will do anything to protect....even if it meant doing the unthinkable...
