After Reincarnating as the Villain's Guide, He Tied Up the Wrong Person

Guide top x Sentinel bottom [Pure-hearted, clueless top x powerful bottom who bows his head for love] Jiang Zhiyi transmigrated into the villain of a tragic romance novel. In the original story, he was the younger brother of the protagonist top, a D-rank guide who became twisted from insecurity over his mediocre rating. He cruelly abused the protagonist bottom, creating a decade-long feud between the protagonists. But now, he's just a rookie guide piloting a starship with an "Intern" sign on it, completely lost when it comes to the star system navigation. "The navigation says the detention site is just ahead. So why is this a bar district?" "Is this really the protagonist bottom? I thought his eyes were a different color." "What did you say...?? I kidnapped the wrong person?!" * The System inside Jiang Zhiyi told him that if he did his best to recreate the plot, he could return to his original world and continue enjoying his wonderful university life. But now everything was a mess. The person who was supposed to be tied up in the back seat of the starship had somehow become the protagonist top. And as the protagonist top's "younger brother," Jiang Zhiyi now had to explain why he'd kidnapped his own brother. Jiang Zhiyi tremblingly unlocked the handcuffs around the protagonist top's wrists and looked at him with round, pitiful puppy eyes. "Big Brother..." Before he could apologize, the protagonist top suddenly grabbed his wrist. "You," the protagonist top said slowly, "form a permanent bond with me." Jiang Zhiyi: ? Jiang Zhiyi: Help! Why is he a siscon for his little brother?! * Jiang Jinyue had been a prominent figure in the business world, but after an accident, he unexpectedly found himself inside a book. He had no memories, no System, and knew nothing about this world. It took him half a month to figure out who he was. He was now a major general in the X-Star Empire's military, a rare S-rank Sentinel suffering from severe mental instability. The doctor told him that he had to find his fated Guide partner as soon as possible and form a permanent bond in order to survive. Jiang Jinyue spent another half a month testing his compatibility with Guides all over the world, but still couldn't find his fated partner. Then, one day, a Guide boy he'd never met suddenly dashed out from the roadside and clamped a white cloth smeared with a sedative over his mouth, a cloth completely ineffective against Sentinels. Pretending to be knocked out, he let the clumsy Guide handcuff him and stuff him into the back of a starship, all the while babbling through some lines like a robot. What a clueless Guide. Jiang Jinyue didn't even feel like taking a compatibility test. He stood up, intending to snap the handcuffs, but accidentally triggered the testing device beside him. "95% compatibility." "Congratulations, you've found your fated Guide partner." * The blurb leaves things open. Both leads transmigrated into this world, and they are not related by blood. 1v1 pure love, adorable top and swoon-worthy bottom, with very strong mutual attraction. Theme: Keep moving forward, even when faced with setbacks
