As I understand, Mao knew all along that it was her who MC worshipped, because she answered in her head to a statement about ice coffee.
Then MC just as well knew all along that it is Mao that she admires as a mangaka, so moving in to next door apartement isn’t really a coincidence.
Is it correct or have I read it wrong? If I am, then this is all levels of creepy...and interesting.
MC doesn't know Mao is the mangaka she admires. She even prays to the author for her to make up with Mao. If she really knew they are the same person she wouldn't do that.
This manga can turn out to be good. There's this setup of impending doom that might happen. If developed properly, it can be interesting. It's just that usually in Yuri, plots like this get outshined and underdeveloped for the sake of stupid highschool like romance, and the world building and plot becomes a secondary theme that is used to just flavor the romance part, or give them opportunities to be together.
