I am not against backstories if a backstory is on point. In this drama, the backstory went on for multiple episodes showing every interaction between the main and secondary characters, most of which were irrelevant to Li Xun and Zhu Yun's relationship and the reason why he went to prison. All I wanted was to see how we got to where the story started in episode 1. Episode 13, and there was still no explanation why ML went to prison and why he was such an asshole. It was just a mind-numbing trauma rollercoaster. In addition to that, none of the characters were likable. ML was just a stereotypical asshole because reasons. Even if there was a reason, it's still not a justifiable excuse to be toxic and treat people badly. He was just an asshole for the sake of being an asshole. And, FL fell in love with him just because the writers decided so. Toxic people and toxic relationships, pass.
