I mistook the title and cover for Reika and ended up getting foolishly excited.
After I read the summary I almost got fooled once again when I read her name Reiko Kujouin and thought for a moment it was Kisshouin Reika.
Fool me once, shame on me. Fool me twice!...I'm still an idiot.
We really need a manga for that one. It's my favorite villainess novel by far. Romance might is really slow but no bullshit where every other character is a handsome male who immediately falls in love with the quirky FMC. (Yea, I'm talking about another novel on a different manga's comment section! What are you gonna do about it!? Report me? Hahah!!...please don't report me.)
