In the beginning of DALS, I didn't like Greg, because I thought he tried to make a move on her at a vulnerable moment. However now, I feel he was probably the best thing that could have happened to Alizée since her marriage broke up. Perfectly suited in dance and I think he can be described as a soul mate too. But the best thing is I think is he seems to love Annily and enjoys being with her as much as if she was her own daughter and it's not just an act to please Alizée and that is priceless to Alizée.
EDIT:
I keep adding to this post. One of the most important things to me in watching videos is I get a lot more enjoyment out of a video if I feel the singer/group is enjoying what they are doing. One of my favorite bands of all time is the Eagles and one of my favorite performances is Hotel California and the part I love most about one of their performances was Joe Walsh and Don Felder. They looked like they were having such a great time there and in this video of Greg and Alizée, they are having a great time and I love the hell out of that.
Finally found the video I was looking for. My favorite part starts around the 4:00 mark,
