Yoseob is ready to show a new side with his latest solo album!

On September 20 KST, the HIGHLIGHT member released his first solo full-length album 'Chocolate Box,' featuring title track "BRAIN."

Reminiscent of a box of chocolates, the album itself is broken into white, milk, and dark concepts, with "BRAIN" leaning into the dark concept with a sensual R&B vibe, dynamic choreography, and lyrics conveying a passion felt for someone who he can't seem to get out of his head.

Meanwhile, Yoseob sat down for an exclusive interview with AllKPop to discuss 'Chocolate Box,' collaborations with pH-1, Colde, Primary, Minseo, and more, as well as his 11-year-long career as an idol. The full interview can be read here.
