I don't even know where to start because the MV overall is so fun to watch. Still, if I have to decide, I just cannot not chose the underwater scenes. They are just so aesthetically pleasing. The colors and mood are suddenly changing, tinting the world in shades of blue which make me realize that there is always more than you see at first glance. 

All the club scenes are fun and the moments that Sammy spends with the pretty girl are nice to watch too, not to mention how cool he looks with the Bella bag... still, the underwater scenes got my heart.
