BEAST‘s Yoseob and A Pink‘s Eunji had a special performance of their duet song “Love Day” on Music Core today.

“Love Day” made its release on March 14 to celebrate White Day, an unofficial holiday in Korea when lovers are supposed to express their love by exchanging candy gifts with each other. Their full music video for the song was also released a few weeks ago on March 13.

The song is also the first track from A Cube’s four season project, “A Cube for Season.” The song was written by Kim Gun Woo, who wrote MC Mong’s “I Love You, Oh Thank You,” “Letter to You Part 2,” and A Pink’s “It Girl.” The lyrics are written by Kim Ee Na, whose previous work includes IU’s “Good Day” and “You & I.”
