the only difference is the title and the cast. It's a Taiwanese version with Wang Jiro as Night and Koo Hye Sun as Guan Xiao Fei/Izawa Riiko...
The Japanese version had the same core plot. However, the J version had way better story lines. After watching the J version, I felt like I want to become like the robot character not just because of the typical strength and special capabilities it has but due to the attitude it portrays to selflessly love someone. Check my review to see more why you should watch the J version.. :)
The story of Zettai Kareshi revolves around a girl who is given a free trial to use a lover-type robot, Nightly 01. It has its fair share of quirks and cool scenes. It is also the same as Absolute Boyfriend, the Taiwanese version of Zettai Kareshi (however, the female lead here is Korean so the dubs might be disappointing).
Both dramas are about girls living under the same roof with robots, who are slowly developing feelings toward them. Zettai Kareshi is cute romantic comedy and Ando Lloyd is sci-fi romance.
Remind me of Yokohama Ryusei drama....& still 1 of my favorite drama....If you like this genre this is a must watch romance comedy drama.
Dramas about human-cyborg relationships with the cyborgs developing human characteristics & understandings
The Japanese drama also originates from the same manga "Zettai Kareshi". Both dramas are expected to share the same theme that is a love story between a human girl and a robot.
