So I remember this one music video with these 4 guys who are a part of this boyband and in the music video they're trying to get their girlfriends back. I think the band is Euorpean and the song itself is pop. I remember one scene in the song where one guy goes to grab his girlfriends hand as she walks away from him, but she just keeps walking and eventually her hand slips out of his gentle grasp, and then he runs up to do it again.

I've been looking for this song for ages but never found it, please help me rediscover it!

It may be a 'wanted' song. I'm pretty sure one of their songs music video is of them running after girls that they used to be with (I guess) but check them out and you might find what you're looking for ^.^
