Excellent. Some hints of grain and pixelation, but only minor.

Audio:

Very good. Only during the opening and ending songs I had the feeling that volume was slightly inconsistent.

Subtitle:

Good HK originals. Some few strange wordings and grammar, but understandable.

Comment:

This show left me somewhat confused. I'm still not sure what it was all about. It's a little bit like "Kanon" with all this childhood promises stuff. Also the character style is very similar. Very slow paced, very melancholic, very confusing.
