At first, Ji Jin thought his life would follow the path others expected of him: from legitimate eldest prince, to crown prince, and then ruler of Huaxu. This vast realm and all its people would be the responsibility he had to bear.
Later, he thought that it didn't matter if his father suspected him, and it didn't matter if he couldn't speak of the one he loved. At least he would have done right by the imperial robes he wore and the countless subjects under his rule.
Only after his death did he realize that his whole life had been no more than a passing line in someone else's book: "What a pity about the deposed crown prince..."
So what if he got another chance?
Ji Jin: A peaceful realm and harmony throughout the four seas are my wish. But in this life, I will also protect that person, ensuring a smooth, peaceful, and happy life for him. I won't let that so-called visitor from another world disrupt my home and destroy the peace I've spent half my life building.
Chu Yi: QUQ Big Brother Crown Prince...
Xiao Tingyan: So I don't have to fake-marry you this time, right, Your Highness Ji Jin?
Emperor Xuande: ...You unfilial son!
A certain Gouchen Emperor Lord, who prefers to remain anonymous: Tsk, tsk, tsk. Ziwei, I never knew you were like this... Weren't we supposed to agree that I was the Great Emperor's principal consort?
According to the records: The Northern Pole Ziwei Jade Void Emperor Lord resides in the Ziwei Enclosure. He is the master of all phenomena, surrounded by the stars. Above, he attends the Golden Palace; in the middle, he commands the myriad laws; below, he governs Fengdu. He is the lord of all the stars in the heavens.
P.S.:
1. The deposed crown prince is reborn. He's still thoroughly upright, but in certain respects, he's probably letting loose.
2. The story involves supernatural elements such as immortals and gods reincarnating and people transmigrating, but these are only there to fill in the reason for his rebirth and won't take up much of the story.
3. Ji Jin x Chu Yi, gong protagonist. No switching, no reversals.
