I was hoping so much it isn't like any other japanese """comedy""", but it, unfortunately, is.
It feels like you're reading the same book over and over again. This genre has nothing appealing or new, it is just another generic story. Speaking of which, it's nonexistent. Time machine? Seriously? Not only it has all the cliches of genre, author didn't bother him/herself to implement a good starting point.
All characters are very unnecessary and annoying, made purely for the drama.
Don't read this, it's just another waste of budget.
I have nothing more to say but the review requires more words. How stupid.
