I became a villain and was harassed by beautiful girls

I traveled through time and became the evil elder sister Tang Xin of Xuanling Sect. I wanted to build a good relationship with the beautiful girl protagonist, Su Ling, the future number one sword god in Jiuzhou, but I was forced by the system to continue to be a "bad guy"... Hey, something is wrong. Why does she like me more and more the more I scold her? Why are there more and more beautiful girls around me? Am I not being a bad guy?
