Fans dissapointed for Lycoris Recoil Ending

Wow, this was a bit too far with a bad ending. I am getting some Game of Thrones flashback, but totally overboard. I watched the ending of this show and yeah it wasn't the best ending. But it wasn't GOT. And it was a great ending to be honest.

I like that final mystery to learn if the main character died or survived their fake heart and how they identified her after what apparently was several months.

That said, the magic that this series cultivate was just thrown in the garbage and burned. And this is what happened with this show.

If you followed the adventures of Chisato and Takina, what are your thoughts of the ending?
