Cheap shit story. Why does Japan seem to love these mayfly romance stories so much?
Why would they believe anyone would give a shit about someone dying for whom the entire premise of the story revolves around them dying soon? It is like saying water is wet.
Also kinda insulting to the genuinely depressed and / or suicidal. As if someone's life can be turned around so easily just because they actually happen to be dying. No, you won't magically get friends for having an invisible girlfriend. It doesn't work like that. Even having a potential girlfriend just conveniently cast into his path like that is making light of the whole process. Bet you wouldn't have tried to make this story if the fat old bloke had been the one watching for him all along.
So basically the whole premise is: Death Plot + Convenient Deus Ex Machina romantic target = Contrived happy death ending.
Plus the story itself is mayfly, being less than 20 chapters long. Guess they couldn't keep the premise going any longer than that, though somehow it dragged on the same shit the whole length anyway.
Boring.
[Edit]: Whoa... I think I'm the first person to ever rate this a 2/10. Or at least so few that there isn't even a bar for it, so I can't check the exact number (3/10 had 12 votes and 1/10 had 178). The vast majority seemed to have voted 10/10 for this piece of crap... but then that is common. Logically speaking 10 and 1 should be the LEAST common votes for anything since most things should, logically, be within two standard deviations of the middle... surely... yet so many people just spam 10s and 1s at everything because they can't help but regard everything in extremes.
... Yeah.
Can't really understate the contempt I have for such mindless meat-lumps.
But even if you're incapable of thinking in relative terms and can only vote in 10s or 1s, hint hint: this would be a 1, not a 10...
