Super Junior's Donghae and Eunhyuk have boarded the retro train for their first project single, "Oppa Has Arrived"! On December 16th, their duet song "Oppa Has Arrived" and Donghae's solo track "First Love" were released digitally through various music sites. "Oppa Has Arrived" carries a disco feel with its lively rhythm and cheerful lyrics. This upbeat dance track sings about how K-Pop is spreading internationally, and that no matter where they go on their private jet, the boys are greeted by fans who scream "Oppa!" Meanwhile, "First Love" (which was written by Donghae himself), is a ballad with a simple melody, accompanied by a piano and strings. Donghae and Eunhyuk plan to perform "Oppa Has Arrived" on KBS's "Music Bank" on December 16th and SBS's "Inkigayo" on December 18th.
