Is There Anything Wrong with Becoming a Tool Person in the Manga?

After learning that Yukinoshita Yukino had an affair with the teacher, Tian Rong, who liked the two-dimensional Yukinoshita figures, cried bitterly, saying that his youthful love story had ended... However, as soon as his eyesight turned dark, Tian Rong was brought to the world of Harmono by a useless system. At that time, Yukinoshita had just met Hikigaya in the service department, and he thought he could rule the world with the help of the system, but in the end, the system was of no use except to increase his favorability. As a veteran nerd, Tian Rong finally came to the world of comprehensive comics in his dreams. He thought he could live a comfortable life flirting with Yukinoshita, Tuanzi and other girls. As a result... The plot development seems a little off. He is actually a pervert known to the whole school. So, this story begins again! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
