could someone tell me how this is related to Hidden Love, and why there actors are different?
it is in the same universe; the main male lead of this show is the brother to the female lead to hidden love. however, they are not connected/standalones, and the actors were changed from hidden love because the roles are just support characters, so dont need big names to play small roles
by when and how does sy comes to know about the absolute horrors committed to wyf
he finds out after they have already been in a relationship for a while. basically yifan gets harassed at work, and he finds out from one of her coworkers and is upset bc he feels like she doesnt trust him. so she tells him the truth about why she left him back then. my guess is probably going to be around episodes 18-20
