I'm not a womanizer for Chihaya Aine

Mygo's second creation was transported to the dream world. He was alone in Tokyo, had no Japanese yen, and could not speak Japanese. He could only bind to the "Iron Blood Single Push System" to obtain money and rewrite his identity and experience.
The system is very strong, but it seems a bit too strong. The reward of "Yuqiu Girls' College Student" directly turned me from a middle-aged uncle into a female high school student. Every time I get a skill proficiency reward, it adds a heavy experience of hard training to my past.
Fortunately, the girls around me don’t know about my false past, otherwise they would think that I am an extremely heavy person, right?
