Love Rerun

Sayaka is a thirty year old office worker dissatisfied with her completely non-existent love life. That's why when she learns her long-time crush is finally single, she convinces herself to finally sieze the opportunity. She asks him to meet her, so she can confess, and... She wakes up in a strange apartment wearing clothes she doesn't recognize. But someone else is there with her whom she does know. It's Machida, her coworker who she doesn't know or even like very well. She asks him where she is, and he tells her: this is THEIR apartment, they're dating, and she even lost her virginity to him.

This manga is probably highly dependent on individual taste, but I personally find it quite entertaining. It's entire concept is about, "what shocking, dramatic out-of-character thing will Sayaka uncover next that apparently she did during the month she forgot?" The drama is so over-the-top that it reads to me almost like a comedy. It's almost as if it were one of those body-swap comedies where the one character discovers to their horror all the things the other person did while in their body, except that even more amusingly, this was all Sayaka, and she just can't remember.

The major downsides to this manga is that it's short, at only two volumes, and scanslators haven't even translated all of it. It's the kind of concept that couldn't drag on too long, or else it would get even more unbelievable, but I think it could have benefited from being a little longer.
