In the Third Year of High School, What the Hell Is the Rebirth Counterattack System?

During the summer vacation when I was a senior, the system came twenty years earlier! Eighteen-year-old Song Han awakened the [Rebirth Counterattack System]. [In your previous life, after being rejected by Xu Ran many times, you became disheartened and gradually lost contact with the twin sisters next door. [New mission: Say a word to the twin sisters of the Su family. [Reward: 500RMB] Is it so easy to have money? Then wouldn't there be no need to work hard in this life? Song Han was planning to rely on the system to live comfortably for the rest of his life. The twin sisters who live next door, the "goddess"'s rich best friend, the plump and well-dressed school girl... All get involved. Song Han fell into deep thought. Why does it seem like I can stop working hard without using the system in this life?
