Aaaaaand there goes my interest in this manga. Into the trash it goes. Sigh...
I decided to check this manga out since I like yuri and I've been digging these "villainess isekai" recently, but this manga was already on a weird position for me since the first chapter. I'm not fond of extremely obsessive characters like Rei and now on chapter 4 we see her using her knowledge of the game to blackmail Claire's father...
Nope, Rei just crossed a bridge there and entered "crazy creepy obsessed" territory and you could even add that she's become a stalker as well now that she's Claire's maid. That's a yikes from me.
Besides, I just can't see Claire falling for her, so in the end this will be another one of those yuri stories where one of the characters becomes lesbian just because.
Kinda reminds me of Yuri is my job. The yuri felt so forced and out of place on that manga that it made me wish I never read it in the first place.
