Oh i get it... they are immortals, and both betrayed each other multiple times... they are at the same time each other heaven and hell, their love and villains
the way I see this these guys are a pair of immortals who are stuck in an endless loop of meeting again, becoming friends/falling in love, and then betraying each other. Just over and over again through out the ages. They both know this keeps happening but they can't help it
Woah these animations are great! The story seems like it has some kind of reincarnation/alternate universe aspect where they're meeting in different times (universes? lives? Maybe a simulation aspect with how they're waking up?). Super fun!!
So, I kind of understand the story? The person with the blue hair I assume had prejudice going towards them. Maybe for their hair color. They are seen with a mob over them running them out. It quickly switches to the white haired guy. He is seen in a workshop with blood stains. So he killed someone or someone killed someone he knew. He gets driven off. The pair are then seen together. They are at a funeral, probably someone they both knew. Eventually they go to a city, one of the twos home cities I’m going to guess. It seems after seeing one man killed the white haired person betrays the blue haired person. Blue person is in jail. After being shot and getting back up, the white haired person betrays the person who shot the blue haired person. They are both seen as devilish. My guess (again) is they took over the place and that’s why you see the two in the final scene outlooking a planet or a moon together. There was a lot of guessing. Good animation though, liked it a lot
