Not the first time I've seen a villainess story following a male MC, the other example I can think of being the novel "Akuyaku Reijo Ni Koi Wo Shite". It was really good, but I didn't like a few choices later on in the story, and for some odd reason. . . the group translating it were unsettling, to say the least. At around chapter 70 or so they made it so that in order to read the chapters of the novel, you had to solve a riddle for every release. Apparently, if you messed up one of them, you'd be IP blocked from their website. Not to mention to get the links to the chpaters you had to join their weird discord.
Honestly a shame, since I really enjoyed my time reading that story. That one went to some dark places, which this manga obviously won't go near, but consider me interested nontheless.
Might drop it if his sister became the heroine, and is a complete fucking degenerate, ala a Heronia or an Akari.
