Some points for the pro column:

• lovable MC
• didn’t focus on the bullying to make her look more miserable
• instructor lady was strict but didn’t physically hit MC with that stick of hers. When it was first shown I feared the worst
• MC isn’t out for revenge
• people around her don’t seem to be vicious to foster sympathy for MC

Cons:

• the OP (which was played at the end) kinda spilled the whole plot. I think I have a very thorough understanding on how this whole show will play out. But I just hope that it will surprise me.

All in all, it’s enjoyable enough for my taste.
