The Disciple's Teachings

Hyeui, the rightful heir of her martial sect, has long been secretly in love with Muyeong, the sect leader who has been carrying the burden of the family in her place. Whenever Muyeong returns from a mission, Hyeui notices that his strength and health are gradually fading... Until one day, he finally collapses. Unable to bear the thought of losing Muyeong after already losing her father, Hyeui decides to take the position of sect leader away from him. But Muyeong is not the kind of man who would willingly give up his title. So Hyeui locks him away in the basement and refuses to let him out until he says the words she wants to hear: that he will hand over the position of sect leader to her. And until then... she begins subjecting him to erotic torture. Original Webtoon
