Louie and Hayana's OST is for new KBS2 drama 'Manhole', and the couple took on a remake of classic group Turtles's "Airplane", adding Louie's own take to the rap as well as Hayana's clear voice. Louie and Hayana announced they were dating to the public back in March of this year.�

In a making film for their OST, Louie and Hayana said, "We are honored to remake this beloved song with our own rap and our own color. It is even more meaningful because it will be an OST for 'Manhole'."�
