Man + women meet at a party, they develop in to a romantic relationship and then weeks on the man becomes abusive verbally.
The women changes in mood, loses friends and becomes a very different person to how she was before the relationship.
There's a shift in mood shown by the colour of the story board. The first storyboard is where the couple meet, nothing happens they just get to know each other and he's really affectionate. There is a blue sky and light colours of the building give of a positive vibe.
Then in the 2nd storyboard his behavior darkens and then 3rd it abusive.
