Usami Kei is a salaryman who has risen in status due to his engagement with Mei, the wealthy daughter of his company's president. Shortly after she breaks off the engagement, a power failure leaves him stuck in the elevator of his apartment building. Trapped with him are three others living on the same floor - Airu, a trilingual interpreter, Ojiro, a model photographer, and Masato, a psychiatrist. While waiting, their conversation hits upon their love lives and the question of whether there is truly only one fated partner for everyone. As a result, they decide to try "shuffling" their relationships with each other.

I haven't watched this drama yet, but a few of my friends said it was good because it was different to your typical J-Drama.
EDIT: I'm watching this drama at the moment, it's really good!

If you get past the first two episodes it starts to get quite interesting

I'm up to episode 9 now, but viikii the main source of the video for most sites has some problems with streaming at the moment >.> so I can't finish it yet
I recommend it to those who are looking for a Romance J-Drama without soppy bits

If you guys have any opinions/ratings on this drama, feel free to reply
EDIT 2: I was meaning to edit this for a while now because I finished it a while ago haha. Viikii fixed the vids so I was able to watch the end of Love Shuffle. Overall, I still have the same thoughts as before

I liked the ending, although I thought it lacked a little something, but I can't put my finger on it...
