What are your thoughts on this idea for a story, it may be cliche but we'll see.
>A beautiful auburn haired woman wearing very odd and extraterrestrial clothing washs up on shore
>two best friends, they attempt to help
>due to the face of mc1 she immediately trusts him but is unsure why, total amnesia except for the face of her lover
>she does have abilities as well, but those core memories will unlock throughout the story
>an gargantuan space fleet of unknown origin is decimating solar systems for unknown reasons
>the mysterious woman is completely frightened by this fleet upon hearing its name, but is unsure why
>mc 1's quest is to assist her in getting her memories back and maybe a romantic bond will form, he actively thinks this in the story, not will they won't they bullshit, hes plotting on that pussy
>mc 2 finds the fleet to be intriguing and would like to steal some of their weapons and data chips so that he can use their power
>they travel across planets, galaxies, solar systems to escape the fleet yet get closer to them, they need a "Star Guide" or something, path of the constellation?
>at some point it is revealed that mc 1 has an 30 minute older twin brother that he never knew of, explains her sudden trust of mc1, mc1 begins to seethe badly
>this brother is the fleets leader
>he is the woman's husband, ripping and tearing through space to find his love
>there is a confrontation
>she does not have her memories back in full, but she does not believe the twin brother
>the distance he came to get her, is inconceivable, why was she cast away from their home galaxy?

That's all I can think of for now, obviously all will be fleshed out, lole politics, galactic kingdoms, how they are able to travel such distances in such short time, FTL is an unproven concept in this world, but there are some people who make personal gadgets that appear to make use of it. It would be like driving to another state, I was considering a galactic rail line or something. But idk, I feel as if I'm just meshing a bunch of random things in my mind whilst writing this.
