Absolute Boyfriend

I was watching this drama a few hours ago... I was not supposed to watch it because I have other things to do. But my friend told me the story is cute, especially the guy. The story was based from a Japanese manga. It revolves around a girl who bought a robot for a boyfriend. Guess what? He is a perfect boyfriend. He is smart, jealous sometimes, caring and sweet. The girl is sure so lucky but she gets irritated when the guy is always around her. The guy even worked at her office just to be with her all the time. Well, I was not finished watching the entire series and I am looking forward for a wonderful ending.
