The Villainous Young Master is Kept by His Yandere Maid

Good news: After transmigrating into the role of a villainous young master, Kane successfully avoided his death plot and retired to the borderlands for a peaceful farming life with his maid.
Bad news: The maid is actually a succubus—a long-hidden yandere. She imprisoned him at the border, lavishing him with obsessive affection that consumed his body and soul. Now she wants him to drink her… No! I’m a man! I need to stand firm! This isn’t the life I want! I’ll shout “NO!” at Enya!
“Young master, who are you talking to? Time for soup~.”
“Coming~ Coming~”
…
Kane thought dodging death meant smooth sailing, but it was only the beginning of greater perils.
His obedient maid is a succubus yandere scheming to cage him;
The hero’s elven mentor stares at him with dead fish eyes, candle in hand, licking her lips;
The icy princess “accidentally” wanders into his room in sleepwear at midnight;
His childhood friend—a phoenix-like overpowered heroine he once bullied—begs him to torment her again.
Something’s wrong. They’re nine-tenths suspicious.
When Kane finally overcomes these trials and returns to his borderland cottage for retirement, he finds the story’s Phoenix Overlord Female Lead waiting in his bed.
Patting the sheets, she smirks: “Hurry over~ Darling~ I’ve been waiting~”
