Hi, so i'll try to explain this in an ambiguous way (in order to not spoil any major plot point): + [KimiAi](https://nyaa.si/view/1655721) will have a bit more explanation on how this world work and stuff but gonna have a sad ending. + [BokuAi](https://nyaa.si/view/1656538) will focus more on the romance side and have a happy ending. Basically it's like two side of a coin (which is connected) so It doesn't really matter which movie you watch first (once you watch either of them you'll understand what i mean). I get the movie from [this torrent](https://nyaa.si/view/1652335)
