Crimson Vale Academy—where reputation is currency, and failure is a stain you wear on your sleeve.Behind gothic walls and spotless uniforms, students aren't just educated—they're measured, ranked, and pitted against each other in a brutal meritocracy. Privileges are earned, not given. The strong rise. The weak vanish.Enter Kairon Vale, a transfer student marked Rank D—the bottom of the bottom. No badge. Just a stitched black fang, branding him as “Obsidian”—a warning to others.In a system where points dictate your value, Obsidian-ranked students claw for every opportunity to ascend into the prestigious Golden or Platinum ranks—where comfort, power, and influence await. But for most, it’s a losing battle.Yet Kairon isn’t here to fit in, impress, or play by their rules. Cold, calculating, and impossible to read, he watches the system… and waits. Because while the academy judges worth by numbers and names—he understands something deeper:Everyone wears a mask. And every mask can be cracked.Let the games begin.

I’ve reincarnated as the reverse harem game’s villainess, the one and only step-daughter of the Eckart duke family.

After a night, surprisingly I acquired a husband!

Well, the fact is that after a one-night stand, I unwittingly signed a marriage agreement.

There isn’t a bad in-law relationship but instead a mother-in-law and daughter-in-law alliance.

The purpose of our alliance: Make my husband interested in women!

Frankly speaking, a man who isn’t interested in a woman … is he gay? Having a husband who is suspected to be a gay, I will fight for him and not let him go astray.

So I raise my eyebrows and with a wicked smile: My dear husband, wait and see how I am going to teach you to be a real man!
