They say that first love never dies. Do you believe it? Haejin does, but Jongwoon doesn't (Yesung). But first love also means first heartbreak. Will time be enough to heal their broken hearts? Is it enough to melt away the love that was frozen back in time?

Kim Jongwoon, also known as Yesung, is the best singer in the whole music department, He's also the leader of the golden trio, KRY, a famous boy band known for the singing skills and good looks. Despite all these, no one else wants to be with him other than s. He's known to be the strict and weird student that no one wants to work with. Everyone is scared of him because he's a perfectionist but that doesn't stop all the girls to love their group.

She's the first girl to challenge the great 'art of vocals' to a duet, the most anticipated performance of the year. Haejin is the type who doesn't give up easily and definitely not to a group of guys who think they own the world. But does Haejin really have what it takes to shake them?

The Time I Loved You is a story about music, rivalry, friendship and love. Tag along as two people find each other at a wrong time and how their frozen love could eventually come back to life.
