First, I didn’t like the rythm it was a bit slow. But I have this feeling for most Japanese romance.
Can be seen at 1.25 or 1.5 speed easyly
Second, didn’t like how toxic these relations was.
But liked the main girl behaviour at the really end.

the Acting is good, there is some plot twist.
I didn’t feel that the support roles was useful except for Meiko.

it was not a bad moment.
Also it's "safe » (Nothing that can’t be watch in public place)
good for a train trip for exemple But nothing really memorable to me
