Huan Yu x Yan Qiuchi
Timid, silly top x gentle bottom
An elder of the Hehuan Sect was fishing by a river when he caught a baby boy instead. That was how Huan Yu came into the world: a nameless orphan, drifting along with the current.
The Hehuan Sect was no place to raise a child. Huan Yu was beautiful, but lacked talent, and had no family to support him. He was often bullied in the sect, and was too meek to fight back.
Until those people found the portraits he'd hidden in his room and discovered that he had a crush on the head of the immortal sects, the beacon of righteousness: Yan Qiuchi.
Their laughter shook the heavens. After more than a decade of timidity, Huan Yu looked at the filthy portrait they'd trampled underfoot and found the will to fight back.
He swore a fierce oath: if he couldn't sleep with the head of the immortal sects, he'd die trying.
And so, in a fit of anger, he went down the mountain.
After leaving the mountain, this Hehuan Sect disciple, untalented, bullied, and with no interest in finishing his studies, was naturally at a loss.
Huan Yu: "I think this is how you're supposed to learn."
Huan Yu: "...Would drugging him work?"
Yan Qiuchi was gentle and kind, known throughout the cultivation world as the head of the immortal sects and the beacon of righteousness. He cared for all living things and traveled far and wide.
One day, he pulled a naked young man out of his bed. Blushing and timid, the youth asked, "D-did you drink that cup of tea?"
Yan Qiuchi replied in surprise, "I did."
The youth took a deep breath, then pulled open the covers, revealing his pale body. "Then... are you feeling hot?"
Note:
1. This is my own take on the cultivation world, with lots of original worldbuilding.
2. The bottom dotes on the top! Huan Yu is the top! The top!! He's a weak top in bed! No switching, no role reversal!
3. If you can't accept that, leave right away!
