Actually, I realized that Koreans generally don't have much creativity. One person writes something innovative, and several others blatantly copy a premise, a part of it, or the whole thing. This idea of a seme not being able to sleep alone has already been explored long before in "An Exclusive Contract." And it's not the only work with this premise.

I’ve read an insomnia Manwha…is everyone just getting equally influenced from one another…antyhow the plot usually different minus that but I always happened to fixate on that tidbit. Kudos to the MC fighting back; that CEO and his fine ass knew better but tried anyway. Until next chap y’all~
