What I mean by that is music videos where the solo singer or a member of the group is kissing someone.
And when I mean "kiss", I mean kissing on the lips. (and not kissing on the forehead like Hongbin did in VIXX's "Error" music video)
E.g. BTOB's Minhyuk having a kissing scene in this music video. I wish I was that girl, just kidding.
And HOLLAND having a kissing scene in his "Neverland" music video.
Also in his "I'm Not Afraid" music video.
Another example is Taeyang's "1AM" (and I find this music video kinda romantic in hindsight because Taeyang and that woman he kissed, Min Hyorin, are married now)
I can't think of any other example at the moment....
Well... this thread is kinda random and, I guess, also a bit of a spoiler.
There probably isn't any 5th gen group (perhaps also any 4th gen group) that has a music video where a member kisses someone because some fans would go bananas.
