Both songs are a part of the drama, "You've Fallen for Me," in which he played the lead male role. Both of his songs ranked number 1 on the Japan ringtone charts.

He played the role of "Lee Shin" in the drama and the song, "Longing" was a song that he had written for his dad in the drama. This song was also actually written by Jung Yong Hwa himself.

This drama was popular last summer and aired in Japan from July to November 2012. This drama has still not died down in Japan as the OST songs are still popular 7 months after the show has ended.

This song also ranked number 1 this past March on the K-Pop OST category as well as the DVD category.
