Building a Story (ii)

So here is a general story idea (which I'm not sure if I will introduce another idea to choose between, but I labeled it as #1 just in case):

I still have more to elaborate on this of course, as you can see. This is a general idea or outline of the story. The words I used to describe the main character and their intentions have a more negative connotation than what I was striving for, so I would need to improve on that to ensure I don't go off track with a different view or bias as I am striving to make the character more ambiguous.

I initially was planning to have the main character kill, but it may be too excessive and lean more towards the evil side rather than anything, so I stuck with sabotage. Sabotage can range from something that just makes things more annoying to deal with to nearly life-threatening, so I think the flexibility of that can help.

I also want to make the love interesting pretty morally ambiguous as well. But since the short film will not be centered around them, it needs to be more obvious so that they don't turn out to just be plain annoying.
