In the second year of high school, the arts and sciences were divided into classes, and the two of them were assigned to the same class by accident. Bian Qian became the class monitor, and inevitably came into contact with Wen Qi.
Early self-study:
Wen Qi: “Master squad leader, how do you pronounce this word?”
Bian smiled slightly: “There are notes below.”
Afternoon self-study:
Wen Qi: “Sir, I don’t have the test paper with me, can I read one with you?”
Bian smiled slightly: “Did you eat the test paper I just handed out?”
Evening self-study:
Wen Qi: “Sir, monitor, I don’t know how to do this question, please teach me.”
Bian Qian looked at the basic question, and screamed in his heart: You got 149 in the fucking math test, ask me what 1+1 equals?
After school:
Wen Qi: “Ban…”
Bian Qian: “Get lost!”
Bian Qian thought that she and Wen Qi had met for the first time, but she didn’t know that this encounter was actually a reunion that Wen Qi had planned for a long time.

- Description from novelbuddy

“Look, I don’t need to be the strongest — I just need to be slightly stronger than the guy trying to kill me.”---Zayn Eldrake was nothing more than a nameless extra in the grand tale of summoned heroes — a disposable swordsman in the legendary Hero of Light’s party, fated to die in an early battle against the monsters of the Apocalypse.But when he awakens in this doomed body with memories of his past life, he refuses to meet the same pathetic end.He knows the story. He knows the heroes. He knows their strengths, their weaknesses… and most importantly, their women.With the power of [Devourer’s Pact], Zayn can consume the abilities of those he defeats, transforming himself into something far greater than a mere extra.Strength, magic, divine blessings — everything in this world is his for the taking. And if fate itself stands in his way? He’ll devour that too.

“My fiance has a change of heart. Your fiance isn’t in love with you. Why don’t we get together and get married instead?” Natalia spoke without a hint of irony to the mysterious man—the embodiment of elegance as the man stood at the entrance to the cathedral under an umbrella on a rainless, cloudy day.

After defying her family’s wishes to marry Vasili and agreeing to retreat from her budding modeling career, Natalia’s life turned upside down when her fiance abandoned her for another rising model from the same company on their wedding day. Amidst Natalia’s contempt, Alex Bruch came into the picture. Natalia thought her marriage with Alex, the man with blood-red lips and violet eyes, would be as mundane as asking each other what to have for breakfast...

Above all else, she would have her revenge.
