What the heck is the point of "pretending" to be a guy, seriously? Last time I check it's meaningless in this world. "Oh but but its mysterious". Bish, we (reader) already know she's a girl, why keep up the stupid charade at this point? Just so we can say Author is an idiot by keeping secret something that's not really a secret?
Guess when you're out of ideas, just keep pulling this nonsense once in a while to keep the readers engage or else the ratings would drop.
