I Alone Level-Up (Web Novel KR) - Chapter 31

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.

“Missus, time to fulfil your duties!” Mu Yuchen demanded as he pulled Xi Xiaye closer with his arms intimately wrapped around her waist.

It was a meticulously planned feast for the powerful. Her fiancé had knelt down on one knee and proposed to her sister instead. Robbed of her right to her inheritance, she was prepared for the Xi family to throw her to the wolves.

“Mu Yuchen, let’s get married!” He looked up at her, then suddenly stood up.

“Where are you going?”

“Let’s go. Any later and the civil affairs bureau will be closed.”

Zhuang Nai Nai: Can’t he speak properly for once?

One day, somebody asked the man, “Why are you always the first one to bow your head every time you two fight?”
