Despite the cover image, this storyline does not in fact sexually exploit mental illness. It features a day in the life of a severely psychologically disturbed agoraphobic girl: she meets her new counsellor; she also receives a visit from a man purportedly her friend, who comes over to have sex with her, give her some money, and reinforce her agoraphobia; and she attempts to overcome her problem. The ending is vague, almost off-putting, but the storyline is engaging right up to that point.
I wasn't too sure what to think of this manga. It really doesn't make much sense and leaves you really wondering what you just read. It is small and a very quick read but left me very uneffected.
