This is the shortest one-shot I have ever read (only 8 pages). The story is simple: a girl imagining how to declare her love for a classmate and her brother giving her his advice, culminating with the confession itself. It's basically 85% imaginary scenarios and 15% real actions. The mangaka tries to make amends between the typical girly love and the typical boy fantasy. The result, in my humble opinion, is hilarious. The art is beautiful, all colored pages. However, there's not much characterization (that would be too hard with just 8 pages) so it's hard to say if there is anything abnormal inthe siblings' relationship or to which extent the heroine's crush is made up of admiration or lust. It's not the most amazing story ever. If you're not looking for something extraordinarily good, don't let the shortness of the work and poor characterization scare you away, though. I found it quite funny (it sort of has a final punchline). If you're looking for something to entertain you those 5 minutes before going to work, this one-shot should do the trick.
