I Became the Handsome Twin Brother of the Novel's Heartthrob

[The author's other novel, All the Fuzzy Creatures in the Galaxy Adore Me, is currently updating] Chu Shi transmigrated into a book and became the kidnapped twin brother of the story's universally adored protagonist. The original owner of his body went through countless hardships before returning to his wealthy family. At first, he was cautious and meek, but eventually grew envious and jealous of the beloved protagonist, opposing him at every turn and ultimately becoming a cannon fodder character who died young. Knowing how these plots usually went, Chu Shi decided to win over his beloved protagonist of a younger brother. So he became his brother's assistant, helped him with his classes, and even served as his stand-in. He became a truly heartwarming big brother. Before long, he realized something was off. His younger brother, the beloved protagonist, clung to him and called him Big Brother, an extreme brocon: "Big Brother is mine. Don't even think about taking him from me!" The cold, domineering CEO: "You're mine! I won't allow it. I won't permit it. No way!" The scheming teacher: "Sweetheart, how about some free one-on-one tutoring?" The aloof, celibate top-tier star: "You're the only one who understands me. I can't live without you!" Chu Shi's parents: "Our baby has suffered so much. We have to make it up to him!" Wait, he only wanted to change his younger brother's dark ending. How had he become the one everyone adored? Reader's guide: 1. The real CEO type as the gong VS a scheming shou 2. 1v1, no betting on love interests 3. A sweet, everyday-life story. The plot and romance develop bit by bit, so it starts slowly. 4.
