My Bootlicking Desk Mate Is Actually the Emperor [Reborn]

Yang Yan was staying with the Shen family. He and their son, Shen Xinggui, couldn't stand each other, and the little wolf cub was always picking on him. One day, they both fell into the water. The rescue team searched for a day and a night before pulling them out. After narrowly escaping death, Yang Yan lay weakly in his hospital bed and watched as Father Shen dragged in Shen Xinggui, who had caused him to fall into the water, and forced him to apologize. Shen Xinggui, usually arrogant and unruly, looked impatient and was about to storm out when he suddenly got a good look at the pale yet handsome face on the bed. Shen Xinggui froze, then smiled. "I'm sorry, big brother." "I won't do it again, big brother." "Please forgive me, big brother." Yang Yan: "..." Why did the back of his neck suddenly feel so cold? Had the little wolf cub been possessed? Yang Yan never would have guessed that Shen Xinggui really had been possessed. Shen Xinggui was the puppet emperor of the Great Yue Dynasty. He ascended the throne at seven, and only gained control of the throne ten years later, after the regent was executed for rebellion. Back then, no one knew that the regent, who had supposedly rebelled, was actually being kept in the puppet emperor's chambers, where they spent their nights in rapturous bliss. And now, no one knew that Yang Yan looked exactly like the regent from all those years ago. *An insidious, unhinged emperor and school bully gong x a seemingly innocent but secretly calculating regent and campus heartthrob shou *Younger gong; ten years apart in their previous lives, the same age after being reborn *Both are reborn; the shou regains his memories later *Both get their hair cut *There is an angst-and-regret arc, but the story is sweet overall (The premise is set; blurb to be added.
