Ok, so you have two options:
Story of 4 seperate relationships with the storylines intertwining and told parallel to eachother.
Story of a guy trying a relationship with a new girl all the while flashbacks to the previous ones breakup. And showing dissonance/similarities between the two.
Which would you rather see 90-120 pages of? Pretend you are the review board of the Austin Screenwriting Festival.
……basically Dakota which sounds better?
