Aloof Master? Why Do I Think She’s a Yandere?

After transmigrating, Su Yuan awakened a Favorability System and a sword spirit root, then successfully became a disciple of Lin Qingli, the greatest sword immortal in the Northern Domain.

Just as he thought he was on his way to the pinnacle of the cultivation world, he suddenly realized there was something off about his master.

Whenever he finished sword practice and went to bathe, he would suddenly feel a gaze sweeping over him from the shadows.

After he taught his junior sister a cultivation technique, he gradually noticed that his master's smile had vanished. Then he found out that while everyone else's favorability capped at 100, his master's started at 100 and kept climbing, one point at a time.

Only then did he realize in horror: “Master, why are you a yandere?!!!!”
