Devil Beside 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
