The Heir Is My Nemesis, and I Was Switched at Birth

Next up: I Thought I Was an Alpha After Losing My Memory --Main Story Complete-- Si Jiayan transmigrates into a rebirth novel as the cannon-fodder character who was switched at birth with the male lead’s family’s child. In the original story, the true heir, Lu Yinzhe, was bullied by the cannon-fodder character from childhood, growing increasingly twisted and dark. Later, the reborn protagonist helps him return to his family. The two join forces to crush the original character, leaving him utterly unable to recover. He rushes over to comfort and help him, and become his best friend! Then he can retire after a job well done. There’s no way this version of Lu Yinzhe would team up with the reborn protagonist to go after him! They can fall in love while he goes off to enjoy a good life. Perfect. Later, when the protagonist confesses to Lu Yinzhe and kisses him, Lu Yinzhe pins him firmly with one hand and smiles faintly. “I’m sorry, but I belong to Xiao Yan. He won’t let me have any other kind of relationship with you.” Si Jiayan, eavesdropping nearby: “...What did you say?” Couple: domineering, sweet, warmhearted, pure, and guileless bottom × outwardly warm but inwardly cold, possessive, scheming top Preview: I Thought I Was an Alpha After Losing My Memory There are two big shots at school. They’re incredibly close, interact sweetly, and have amazing chemistry. Before Yan Yu lost his memory, everyone secretly hoped: Big shot Yan Yu is so alluring, he’s bound to present as an Omega. Alphas and Omegas can’t be bros, so just get together already! After Yan Yu lost his memory, he casually shoved away a tall, strong Alpha and pointed at Jiang Yin. “Come on, see you in the sparring arena.” Everyone’s hopes for the couple shattered: Oh no, two Alphas have no romance in them. Are the two big shots about to fall out and turn against each other right here? Then, on the day Yan Yu presented, a sweet, tempting pheromone scent drifted from somewhere in the arena... He really was an Omega. Tsk! Jiang Yin licked his lips, planted one foot on the defeated opponent, and casually rubbed his lips. “What did you smell?” The defeated opponent trembled pitifully, reading the room. “S-sorry, Dad Yan Yu. He’s totally Alpha, right?” Jiang Yin glanced over. Everyone nodded like quails. “Totally Alpha!” [Weeping on the inside] Later, Yan Yu kept thinking he must be suffering from a post-accident condition. “How could I possibly be an Omega?” Jiang Yin subtly draped an arm over his shoulder and chuckled. “You’re an Omega with my pheromones on you.” Yan Yu: “...” Jiang Yin lowered his eyes. “Want me to help?” Completely unaware, Yan Yu tugged open his collar. “Yes.” Strong, aloof-on-the-outside but warmhearted beauty bottom × scheming, obsessive top with a mind full of wicked ideas P.S. 1. Alternate universe, with some original worldbuilding 2. One-on-one, happy ending 3. ABO school story, no children, all sweetness~ Theme:
