I don't like every details but the author was like super angry that people especially foreigners are reading their manhwa on a pireted site. They said like they should die. She doesn't care if someone is not financially unable to buy their manhwa. She even death threated a fan who was reading legally.
One does not exactly need a sad backstory. His roots were pretty clear - gangsters/family or corporation of loan sharks, quite spoiled in the context of how they primarily view people esp if they are not family. Grandpa said he used to be hard on alpha/omega traits.
Pretty sure they just mellowed out over the years, esp when their business is now stable.

It's lowkey hilarious how author didn't even tried to give taeju a sad backstory. It goes to show that even you have a loving family your personality can be shit.
Also with the author's Twitter tantrum. Big talk for someone who romantacize rape. Like we never address it properly.
