Developed Narrative

We have started to develop our narrative and make it less mediocre.  We decided we need to establish the relationship first through various ways and need to set the scene for them more, take them out to places and having dates.  We then need more of a reason for the break up instead of them just arguing, we need to make it look better and have better story telling.  We will most likely use the same people who were in our narrative before as they are both A level drama students who are good at acting and know what they're doing.
For the first minute or so we will establish a happy relationship with everything going well and it being okay. Then we will show it becoming a little bumpy with a couple problems which will develop into the true arguments leading to the inevitable breakup
