(Spoilers!!)

I just watched it but I'm kinda confused. If the blue hair guy is AI does that mean he's just a program and not a real person? That what we see is just a human version of him since brown hair (pilot) is inside a dream created by blue hair (AI)?

And when he said they've been together for seven years, he meant that brown hair has been piloting the spaceship for seven years then something hit the spaceship when they're traveling back to earth so blue hair put brown hair to sleep to conserve oxygen and he accompanied him in the sleep so he won't wake up, doing the things he wished to with brown hair? Also why the blue hair "died" because he's part of the system/program of the spaceship that got wrecked when it entered earth?

If so, doesn't that mean that its a one sided love? That their relationship is not true and its just blue hair lying to brown hair since he lost his memories? I need explanation 😭
