As other reviews have mentioned, the story is very simple. The characters are bland and shallow. You have to believe in love at first sight, because certainly there are never any reasons for the characters to fall in love.
The art style has moments where it's excellent, but the animation is frequently very lazy. Even by OVA standards, the budget here feels low. Even when the art style is at it's best, to me it feels like a SHAFT wannabe.
For me the saving grace of this show is the soundtrack. The first episode in particular has a wonderfully emotive soundtrack that perfectly accompanies the events of the episode. The soundtrack alone elevates this show from a 5 to a 7 for me.
