The Villainous Master and His Yandere Disciple Made Up

[Two male leads, powerful and devoted couple, yandere, System, historical romance, master and disciple] A gentle, sunny master as the top, and a scheming, yandere disciple as the bottom. I've transmigrated into the role of a vicious cannon-fodder master. Help! Yuzhen doesn't want to die young, much less be tortured to death. Better grab hold of her little disciple's coattails, and fast. Can't sleep? Come sleep in my courtyard. Hurt? I'll put medicine on your wounds. Too skinny? I'll fatten you up and make you fair. No weapon? I'll get you a divine weapon. The more I look after him, the clingier he gets. I've raised him into a delicate, well-behaved little flower. Great, now I won't die. Except after he was poisoned one time, my obedient disciple started acting strange. Every day he demands that I take responsibility and become his cultivation partner. For the sake of an important plot twist, I had to steel myself and throw my good disciple into the Infernal Territory. I didn't expect him to come back so soon, or to start playing the whole locking-someone-up game. This is ridiculous! Two male leads. Two male leads. Don't read it if that's not your thing.
