Villains, Don't Become the Protagonist's Master

A truly villainous bottom, consumed by obsession x a true protagonist, a deceptively sweet top

Blurb:

As a notorious villain, Xian Qingchen had just wiped out the protagonist's entire clan. Three paths lay before him.

One: Keep hunting him down, and fulfill the protagonist's achievement: Avenge his family.

Two: Imprison the protagonist, and fulfill the protagonist's achievement: Endure humiliation.

Three: Take him as an adopted son, and fulfill the protagonist's achievement: Betray his master and ancestors.

No matter what he chose, he'd get stabbed. Better to take a risk than sit around waiting, so Xian Qingchen took a different path. He hid his identity and became the protagonist, Chu Huizhou's, fake master. At last, the protagonist became completely obedient, calling him Master this and Master that, and saying he was the best master in the world.

Unfortunately, his scheme was exposed. He failed utterly as a villain and as a person, though at least he died a glorious death.

When he was reborn, the protagonist had already ascended to immortality. Xian Qingchen put the past behind him and wanted to start over.

But protagonist Chu Huizhou wouldn't give him the chance.

Chu Huizhou had been a handful even as his disciple. Now he'd ascended and become an immortal venerable, but he was still a handful.

Come to think of it, no one had ever said the protagonist was gay, had they?

He never expected Chu Huizhou's feelings for him to be so persistent, so persistent that the noble, righteous, overpowered protagonist nearly turned into an even bigger supervillain than he was!

He runs, the other chases, and he has nowhere to escape!

Was he really doomed to get stabbed? (Not that kind of stabbing.)

Silence...

Chu Huizhou: "Master, love is the most wonderful thing in the world, isn't it?"

Xian Qingchen: (Admits it through tears) (And enjoys it)

One-on-one, happy ending, both leads are each other's only partner
