I'm 100% sure it's going to be a happy ending, regardless of the novel/manhwa source.
Remember, the reason MM transmigrated into the novel was because she trashed the plot of the novel and the novel's ending.
Her exact words: "What's the difference between this ending and a scam?"
The story is self-aware, and therefore, I fully believe the writer wouldn't give us a "scam" ending.
It will be a satisfying ending. And it's not gonna be a sad one, because after all, the journey of ZQ accepting himself and falling in love with MM, the only ending that makes sense for him is for him to actually live out this newfound life with MM. And also for MM, after everything she will go through with ZQ, the only thing that makes sense is for them to have a HE.
I know bad endings could be satisfying for some other stories, but not on this story. Especially with the tone they've set up in the beginning.
So enjoy watching everyone! And let's all look forward to an ending that is not a scam.
