This drama was boring, unrealistic, and filled with a lot of unnecessary scenes to get to 70 episodes. It started off interesting, the close knit relationship between a brother and sister, the meeting of a soul mate, and just watching a circle of friends progressed through life. However, almost every episode one of the characters would have a life threatening prognosis and the lead girl ( omg sooo annoying ) didn't seem able to talk or exert herself when she needed too. Later on in the show, we encountered a revelation that the siblings are not blood-related and the brother now wants to have a romantic relationship with the person whom he once called sister. Not only is he emotional and angry that the girl does not want to cross that boundary ( thank you!), but until the end he is a depressed weirdo pining over his sister. Now let me get to Wallace Chung’s character, I was brought to this drama because of my love for him. At first, I liked his character and he was wonderful to the lead girl, but later on he was an asshole. The reason, because of his child hood friend that was in love with him. He kept his childhood friend the whole time around him, letting her be VP for his company, and asking her for help like she was the only one who he trust to help run the company, knowing that she loved him. Not only, did he not vocally tell the girl I only want friendship, when she ask him how he felt about her twice he would just have this disgusted look on his face. Now I agree that 90 % of this was her fault because you’ll know when someone does not like you, it doesn't take you 20 or 30 years to come to that conclusion. However, what made Mr. Chung character an asshole is because he kept calling this girl his friend while he mistreated her. He actually proposed to the lead girl in the friend ‘s house. Like who does this! I felt like he didn't want to hurt his friends feelings, so she wouldn't leave his company. Which she did eventually after he married the lead girl and he still was trying to make her stay, I hated his character for that. That girl wasted her whole life on hope. This drama was horrible.
