This 4 episode OVA is a very slow and deliberate romantic story, no humor or violence. Alot of introspective dialogue. Video: 5/5 Perfect from what I could see Audio: 5/5 no popping or muffled noise Subtitles: 5/5 Seemed to be near perfect timing and some very very minor spelling mistakes here and there which I don't deduct for. Good to watch but don't watch if you are tired it will probably put you to sleep ^_^
