Both leads are virgins; one-on-one romance; multiple worlds
Yan Qing is a tree.
After gaining sentience, he became a tree spirit.
Life was happy and carefree until one day the Time Administration showed up at his door and offered him a steady government job...
The reason? After the founding of the country, spirits aren't allowed to become monsters!
Yan Qing: Hello? He became a spirit before the country was founded.
Still, Yan Qing was quite pleased to have a steady job.
And the job the Time Administration assigned him: win over that tragic, beautiful, powerful protagonist?
It didn't seem... all that hard, did it?
World One: Don't Pick Up Slaves from the Arena (Western fantasy)
A gentle aristocratic young master who occasionally goes mad, as the recipient × a taciturn, untamed slave, as the pursuer
The veterans at the Time Administration all said that as long as he followed the System's calculations, he could reliably reach 80% conquest progress and complete the mission!
Yan Qing made a mistake on his very first mission:
Trees sometimes go wild;
He picked up a filthy slave at the wrong time;
The slave had so many wounds that treating them would be a huge hassle;
His friends all advised him to get a different slave.
Yan Qing stroked his chin, thinking that a good tree never lacked patience.
Give him a wash and a little care. Look! He's handsome again, right?
(Other worlds to be decided)
World Two: Don't Pick Up Handsome Men by the Roadside
A rich, foolish, spendthrift young master from a landlord's family, as the recipient × a battle-worn prince with amnesia, as the pursuer
In the fourth year of Tianheng, Lu Huaichuan, a prince of a different surname, disappeared on his way back to the capital. The emperor was alarmed, then posted notices and sent troops to search for him.
People throughout the country were moved by how highly the emperor valued Lu Huaichuan.
But anyone with eyes could see that after a month of searching, the emperor's efforts were all sound and fury.
Two months later, even the posted notices had disappeared.
By the third month, no one at court spoke any longer of Lu Huaichuan, the powerful prince whose achievements threatened the throne.
Meanwhile, in Wuzhen, Jiangnan, the most cherished young son of the wealthiest family, living in the finest house in town, brought a man home.
Yan Qing had arrived early.
First, he enjoyed several months of vacation without any missions.
When he heard the System announce that the protagonist had appeared, he had the servants stop the carriage, as if just to watch the fun.
He'd originally planned not to get emotionally or physically involved this time, unlike in the last world.
But while watching the scene, he realized that this prince of a different surname, Lu Huaichuan,
looked exactly like the man he'd slept with in his previous life.
Yan Qing's thoughts raced around and around.
With a wave of his hand, and amid Shiliu's screams, he picked the man up and brought him home again.
