I just finished this drama, and found it really awesome. First of all because I got to see Tamaki Hiroshi (a.k.a. Chiaki-sempai from Nodame) , DAIGO and Matsuda Shota (a.k.a. Nishikado-san from HYD)
At first I didn't want to watch this drama, because I thought it will be some kind of weird drama where 4 couples will change their partners, but in some kind of twisted way, but this isn't tha case.
LOVE SHUFFLE is about finding the meaning of true love and the importance of each others existence in this world. It has many comic parts and I also liked so much the friendship btwn the 4 leading characters. I was pretty pleased with the ending and also excited about it.
We have Usatan (Tamaki Hiroshi) who is engaged with Mei, but then one day Mei decides to cancel the engagement.
Then we have Aiai (Karina) who has a relationship with Yukichi (DAIGO) but wants to end it for good.
There's also O-chan (Matsuda Shota) who is a cameraman and has a relationship with and older woman who is married.
And finally we have a pshyquiatrist Kikurin who wants to stop his patient Kairi from committing suicide.
The 4 leading actors found themselves trapped in an elevator and then talked about love issues, this is the beginning of their friendship and also the beginning of the Love Shuffle "game". They decide to switch partners each week and found out what their true compatibilities are.
This leads to very interesting sets and comic situations.
