Caught up with the series and I noticed that the fmc is very reminiscent of Mochizuki Amane from If My Heart Had Wings, which probably predates this story.
Both are savant level geniuses, awful in anything but science, forget to eat or sleep properly, hyper focused on tasks, lack any real world experiences, common sense, repeated years, have similar figures, lonely, and etc.
But it seems like FMC is far more emotionally intelligent, has a complex over her repeated years, unlike Amane, and seems more determined to overcome her failures.
Really interesting stuff, since Amane's route was my all time favorite in the visual novel.
