>>280458580 (OP)Assuming you are being serious, some other anons would probably explain in detail better than me,
But there was this chapter in manga where FMC was acting all blushy and enchanted by this doctor guy that seemed to be also into her. She even said to MC she was thinking of leaving their group and staying in the hospital to be tutored by the doctor, something MC accepted despite hating the idea of her leaving, because he wanted he to be happym
Now, its not clear if the author planned all of this or not, but literally the next chapter everything got solved after MC went all depressed and almost gets killed by zombies but then FMC went after him and explained she was only being hypothetical, that she wouldn't leave him, that she loved him, and was just told him she would leave to try to get a reaction out of him.
NOW, I mentioned that it was unclear what the author planned, because, as expected, readers got royalty mad about the NTRbait so maybe he solved things in the next chapter as sn improvised way to solve an scenario he had initially planned to go to longer.
Apparently according some anons, this affected the manga stats and the chance of getting the second season
