The idol will be collaborating with rapper JUSTHIS for "Love Affair 2", which will be a companion single to Niel's solo title track "Love Affair" released last February. 

The lyrics, going under the theme of asking an ex-girlfriend if she's doing okay, seem to hint that the singer still has feelings for her. Niel's "Love Affair 2" is set for release on September 21 at 6PM KST.
