Yin Nianbei transmigrated.
She became the only daughter of the Marquis of Pingyuan in the Northern Territory, and the Crown Prince's betrothed.
She assessed the situation: her fiancé was handsome, he would become emperor in the future, and her future in-laws were easy to get along with. This was a fantastic deal.
So she settled comfortably into the imperial palace, eating and drinking every day, gossiping with the princess, watching plays with the Second Prince, and casually observing life in the Eastern Palace.
Then one day, she noticed a problem.
The way the Crown Prince looked at Tutor Shen was a little off.
The way Tutor Shen looked at the Crown Prince was a little off, too.
The Crown Prince refused to take his medicine when he was sick, but would drink it if Tutor Shen fed it to him.
When the Crown Prince fell asleep, Tutor Shen would drape his outer robe over him, moving with the practiced ease of someone who had done it ten thousand times.
When the Crown Prince told her "Good night," Tutor Shen was nearby reviewing memorials. But she noticed Tutor Shen's pen pause for a moment.
Yin Nianbei: ...Wait.
She opened the script for her transmigration and discovered the title: "After Becoming the Crown Prince's Betrothed, I Discover He Has a Crush. It's a Man."
Yin Nianbei: ???
Theme: His Highness the Crown Prince has been awfully troubled lately. Someone at court keeps setting traps for him, his father keeps stealing his things, his second brother's parrot curses out the whole imperial palace, his third brother charges straight into trouble every few days, his fourth brother secretly trips him up among the civil officials, and his fifth brother... his fifth brother is still watering flowers. Then he realizes he might be a little too attached to his own tutor. Then his Crown Princess-to-be transmigrates here, takes one look, and says, "Your Highness, do you like Lord Shen?"
Crown Prince: ...I do not.
Shen Hexuan: Mm, His Highness does not.
(Shen Hexuan's lips twitch.)
