DinDin and Min Kyung Hoon have just released their new duet single!

On July 19 KST, DinDin unveiled the single "I Should Not Have Loved You," the second pre-release single for his upcoming mini album. The release comes roughly four months after the first pre-release single "Can't Fall In Love Again."

The song, which was written and composed by DinDin himself, features Min Kyung Hoon and is an emotional rock ballad where the protagonist of the song expresses regret over falling in love, as now that the relationship is over, all that he has left is pain. The music video matches the theme of the song, focusing on a couple's happy memories that have since become bittersweet, played out by LOONA's Heejin and 'Mister Sunshine' actor Lee Jung Hyun.
