From the 2 volumes I have read so far, this is quite an entertaining read!
Story: Yamada, the school deliquent accidently falls down the stairs kissing the schools brightest student, Shiraishi and switching body's with her. Switching body's with someone is a story we have all heard before, but Yoshikawa Miki makes it her own and a good page turner, it has a little bit of romance without the added melodrama and plenty of comedy. Although if you're offended by panty shots then I recommend to stay away from this one.
Art: Not bad but nothing special either. Although I laugh at some of the expressions Yamada has, cover pages are good with nice detail, the coloured ones add a nice touch as well.
Characters: It's what can make or break a story, I personally find the characters interesting with enough depth to understand each of them without it being dramatically over the top. It can be risky introducing new characters 'all' the time, but all are likeable and certainly make the story more enjoyable.
Overall: Originally I only read this because I was bored, unexpectedly it was better than I first thought after reading the basic plot. This is a manga for your to read list, so when you're bored this will certainly kill time nicely. Although it's a short review, (there are only 2 volumes so far) I will edit this in the future and continue following the series.
I have to say that I was quite surprised at how much I was enjoying this manga when I first started reading it. I thought it was going to be a generic harem but it's plot device is quite unique and every chapter is very entertaining.
