Main male lead was celebrated for having countless negative traits, being selfish, and having everything handed to him on a platter.
While Mr Han was painted as a "villain" in the eyes of the guys from the team at Samsan tech, while HE was the one with the good traits as well as the tragic backstory, making him a guy you wanna root for.
Unfortunately, this mix made me dislike the main couple - making this a very unique kdrama, to say the least.
