The Disciple’s Lesson

Hyeui, the rightful successor of her martial sect, has secretly been in love with Muyeong, the sect leader, who has carried the burden of her family in her stead.
Each time Muyeong comes back from his mission, Hyeui notices that he seems to be getting weaker and weaker…
And then one day he finally falls down.
Not able to bear the thought of losing Muyeong again after having lost her father, Hyeui decides to take the role of a sect leader from Muyeong.
However, Muyeong refuses to give up his title willingly.
So, Hyeui locks him up in the basement and does not let him out until he says what she wants to hear: that he will give her the title of a sect leader. Until then, Hyeui starts torturing him.
