O Demônio Ao Seu Lado (2005)

"Newlyweds" Keiichi and Akira Hirose have moved to a new city. Keiichi, who works as an author, and Akira, who works with kindergartners, are hiding a big secret from the people around them.

~~ Adapted from the manga series "Saraba, Yoki Hi" by Akaneda Yuki

Sadic, cold, demoniac and bad boy style male leads.
Female leads, on the other hand, are lovely and cheerful.



It is it


..........

Both deal with a forbidden love between step brother and sister. Though I really liked Triple because of this theme (and the figure skating), and wish it had ended differently. If you feel the same way, the Devil Beside You may be a perfect drama for you.

Hi My Sweet Heart and Devil Beside You are pretty similar.
-Both shows feature Rainie Yang as the lead actress in the romance story
-Both are slow paced, and use common Taiwanese phrases and dialogue
-Both feature the heroine encountering romances with several male actors

It has similarity because the guy like his own sister even though they're not blood related, they like arguing about everything, and both the lead male mostly bullied the girl to get her attention
