It did caught me by surprise! Yeah, it's the usual sci-fi anime with generic main plot, but the animation and how they portrayed it in an emotionally gripping way made me stay for it. I already see the tragedies coming, however, they still managed to affect me. I'm thrilled that this one piqued your interest and looking forward to reading your take on this anime.
Btw, you're welcome and thanks for reading through my review! See you around 𓁹‿𓁹
