Donghae (이동해) and Eunhyuk (은혁) are both members of the South Korean super idol-group Super Junior (슈퍼주니어). They are known as the EunHae couple. On Super Junior's 3rd Asia tour in 2011, Super Show 3, they performed I Wanna Love You together, which they had composed and written themselves with Chance of 원웨이 (One Way).

For Super Junior's 4th repackage album, they worked together on the track 여행 (A Short Journey). It was composed by Donghae and written by Eunhyuk. Eunhyuk has said he thought about Kangin, the member who has gone to military, when writing the song. Even though he was banned from band activities for a year, Kangin (강인) was featured on this track after Donghae convinced staff people to let him sing. They also worked on remixing Shake It Up! with One Way Chance for this repackage album. Read more on Last.fm.
