Reading this manga, I've come to the conclusion that there is something even worse than the "I fell in love at first sight", the "cute girl and delinquent pairing" or the "naive girl falling in love with the experienced prince of the school" clichés of shoujo romance.
Story - 2
This manga took the well-known "boy that bullies the girl he likes" plot, and took it to the most annoying level. The guy thinks the girl should do anything he asks her to do, with no regard whatsoever for what she feels or wants, he manipulates her by means of threats... and she just goes with
it. Does this manga aim to tell us that we are supposed to put up with anything if we are in love? But this couple dynamic alone wouldn't make the manga necessarily "bad". There are other mangas with similar plots that aren´t as bad... and there may be even good ones. The issue here probably lies in the character development, or lack thereof.
Characters - 1
From what I've said about the plot, one can already imagine how the characters are like. He's a bullying, selfish brat. She's just a stupid girl. The most annoying characters there could possibly be. This kind of couples are usual in shoujo manga, but longer mangas generally allow us to discover some kind of aspect in the characters that makes us look at them in a different light and start liking or understanding them. This manga, being a one-shot, doesn´t give much room for character development. We are just left with the horrible first impression.
Art - 7
The only reason to give this manga a couple of score points is the art. It isn't particularly outstanding but it's nice, more so if you go for the cute girl and the handsome bishounen guy types.
