On the 17th, Kakao Entertainment's global K-pop representative media, 1theK, released the music video for 'Couple', sung by Apink's  Eunji and Seo In guk through 'Beyond the Studio.'

Eunji and Seo In guk sings about the exciting confession of two people beginning a new love, set against a fresh spring campus backdrop. The youthful and charming visual aesthetic of the video blends with Seo In guk’s refreshing vocal power and Eunji’s sweet voice that embodies the essence of spring.

'Couple' is a remake of the hit song of the same name by the group Sechskies. The song has been reinterpreted with a fresh spring-band sound.

Arrangers Aaron Kim and Isaac Han participated in the arrangement, adding a more refreshing band sound to the familiar lead melody intro of the original track.
