Story:
It was good. Well it made me clench my fist everytime the bullying scene appears.

Acting:
I'm not a pro in this case. But judging from how much i got immersed into the story, the actors really did a great job.

Overall:
If you think it's boring, just keep watching. It's getting better.
Just dont try to think of whats gonna happen next and go with the flow, you'll enjoy it!
Well at first i dont understand what the ending, but after rewatching i kinda get the hang of it.
