This anime was quite a fresh breathe of air. If you are into gender bender this show is just for you. There is no magic or anything. What we have here are fraternal twins swapping lives and each trying to solve each other's weaknesses. I love the relationship between the brother and sister. Also for once, the sister is the older one, unlike the usually "onii-chan" cliches.
The other thing the show deals is the reality of the entertainment industry. Lots of bribing, scheming, and bullshit are portrayed well in this show. There is also even a romantic subplot for you too root for.
The animation wasn't very good, but Chinese anime are improving. The visuals are sparkling. The songs are okay, take it as you will. Finally, there is even hint of a season 2 in the ending too.
