long story short it's a visual novel about a mecha engineer who is drafted to serve in the military because his father was a war hero, and he ends up working helping a four man team of pilots and he can choose one of the four to partner with. from there, each pilot has a romance story to varying degrees of success.
a little more in depth, the first pilot is a sociable carpe diem explosives specialist. his romance path is more about the protagonist learning to come out of his shell and experience life rather than retreat into the comfort of escapism. The second pilot is at first glance an ideal and noble soldier with strong ideals, who ends up being a convincing narcissist who doesn't have any interest in the protagonist but encourages him anyway to feed his ego. Third pilot is a gruff misanthropic recluse who, while actually quite intelligent, is tough to get along with and his romance is about him and the protagonist finding the right give and take and that they can care for each other the way nobody else has in their lives. He dies during his route and the protagonist commits suicide. The last pilot is the commander of the group, and a friend of the protagonist's father. He's a womanizer and sexually deviant, as well as extremely manipulative and abusive. His route is more of an intense passionate toxic romance that gets to the more fantastical parts of mecha as it progresses.
General themes running through the stories will likely revolve around humanity and it's future or stagnation, posthumanism vs transhumanism vs humanism, what is the self and consciousness, various cognitive philosophy things, is humanity stuck repeating the same stories ad infinitum regardless of the trappings of any era or is it possible for new things to happen and if so should they? I haven't settled completely on the themes and am still in the beginning stages of writing
my ambition far outweighs my ability, at least w art
