Lol read the last two chapters.
And literally this chapter just showed you that it’s wooyoung’s older brother and the king black haired guy is the lover/childhood friend of said older brother.
Long black haired guy was the one woo young hired to background check cha kyungju and pretty much has become a lackey of the woo family.
If @langwangji is right then I don’t know how many more there will be. I kinda wish they just made an entire spinoff instead of turning them into side stories. I feel like side stories are meant to be short and not as in depth as the main. It’s supposed to be a fun extra but idk. Who knows what will happen
who’s the guy with the long black hair and the other characters? i’m not paying attention.
