Obviously a pervert, but suddenly terrifying

Zhou Bing from China is an outstanding science college student who has experienced all-round development of morality, intelligence, physique, art and labor. One day, when he woke up, he found that he had changed into another appearance. If he guessed correctly, this should be... ...yes... let's time travel!
And this world is completely another version of the earth, and he has traveled into the body of a handsome young man Akiyama Shun in the RB country on this earth.
After accepting the memory of Shun Hara Akiyama, I learned that the original Shun Akiyama ended up completely depressed after saying perverted words to a beautiful mixed-race girl who had just transferred from another school, and seeing the girl's disgusted eyes.
Uh... As for why Hara Akiyama Shun would do such a thing, there is a strange system in his head that must force him to do such... quite perverted... things.
"Uh, is it possible that I also want to inherit this perverted system?" Zhou Bing thought fearfully
But obviously Zhou Bing is very lucky. Since he became Akiyama Shun, he even mutated the system, and this new system seems to be a bit terrible.
Since then, the new Shun Akiyama has been forced to receive the attention and... harassment of beautiful girls because of the system.
