I was gonna ask if this was worth the read honestly cus I was scarred and freakin pissed from the first novel. Not only did he rape and brainwash that b but also blackmailed and raped other bitches, including his own damn partner! And not only that, mc starts liking him?? Idk man, after that I just got thee biggest ick from top semes that gave a single ounce of energy like that bitch of a trash seme. Him and seme from C&R
No, you're okay without following the main story. I did read it a bit(?), but it doesn't really matter. But you might be wondering about some names or organisation they're going to mention. Not really important because this story's mainly focused on Xinlu and Yuri relationship without giving much spoilers of the main story...

Do you need to read the main story to understand this?
