My Senior Sister Is a Cat Lover

I am a tiger. In order to cultivate, I have mixed up with the human sect. In order not to be discovered and suffer from skin cramps, I just want to choose a peak with few people to survive and develop. And my only senior sister, unexpectedly, was gifted with a divine pupil. She could tell at a glance that I was not a human being, and then she wanted to rob me. She also asked me to accompany her on missions every day to show off in front of others. Senior Sister: "Dear Junior Brother, let Senior Sister touch your head." Male protagonist: "No!" Senior Sister: "Obey! I'll touch you" (tremor)
