First let me begin with the few good things: the concept (not the story) is good the animation is great and first opening song is outstanding.

This anime had a good start but it rapidly turned dull. I don't get the hype and high ratings.

The most boring part of this anime are the characters. All they do is talking, whining, weeping. Every single encounter turns to an endless depressing whirlpool of a should've, could've, would've but we didn't.

Not to mention the cringey pep-talks.

Basically too much talking very little action.

PS: ending an episode on cliffhanger is fine, but having no continuity in the next one is simply frustrating.
