The first episode was very chaotic to me. It went back and forth without context, it was very confusing.
luckily it didn't take long. Once the story really took off, it got very endearing and I really fell in love with the characters.

i say characters, not actors, 'cause personally I think the acting was a bit of a letdown. There were times when the student was supposed to be crying but it looked more like smiling, almost laughing to me.
I can't believe no one in production noticed this.
Luckily the story made up for it. Especially the last episode gave me the warm and cuddly feelings quite a few times. So all in all, not bad
