Yuu Watase's Absolute Boyfriend is the latest manga to head to the stage. AmiPro, who brought Watase's Fushigi Yuugi to the stage, will be producing an Absolute Boyfriend play, scheduled to open in Tokyo in March, 2013. The cast has not been announced.
Viz has released the manga in North America. From their series description:
Rejected way too many times by good-looking (and unattainable) guys, shy Riiko Izawa goes online and signs up for a free trial of a mysterious Nightly Lover "figure." The very next day, a cute naked guy is delivered to her door, and he wants to be her boyfriend!
Has Riiko died and gone to heaven? The cute guy turns out to be sweet, smart, a great cook, and lots more. And he looks like a million bucks, which is what he's going to cost Riiko if she doesn't return him in time...
Absolute Boyfriend was previously adapted into a live-action Japanese drama. Taiwanese and South Korean versions are also planned for this year.
