Love can be painful and hurtful, like a song.

On October 2, Shin Hye Sung's new song, "Like A Child" is an OST for "Discovery Of Love."

The song breaks open the emotions of the three actors of the dramas who go through a love triangle as Summer finds her love for Taeha, while dating Hajin.

As Summer and Hajin prepare for a breakup, Shin Hye Sung's sad voice matches the scenario and helps the viewers relate to the emotions of the actors.

Particularly the last line of the song, "I Love You," shows the characters' truthful love to one another.

Shin Hye Sung decided to participate in the OST of this drama to support Eric's long waited comeback as an actor.
