Lu Wang was the son of Jiangcheng's richest man, who was raised in poverty. He thought that college life would be as boring as high school.
As a result, before university life officially began, Lu Wang rescued a stunningly beautiful woman from some thugs, but after kindly taking her to a hotel, he ended up being slept with by the woman!
What I thought was just a ridiculous experience turned out to be her sister's best friend, and also my university professor and class advisor!
Is this an attempt to make me a rebellious disciple?!
Looking at the mature and sophisticated professor on the podium, who outwardly pretended to be aloof and cold, deliberately acting as if they didn't know her well.
"Lu Wang, why didn't you come to class last time? Come to my office after class."
In private, however, she is quite affectionate and even has a bit of a yandere personality.
"My little darling, I was wrong. I want kisses and hugs..."
She targeted him, and he retaliated.
She tried to avoid him, but he insisted on clinging to her.
With her incriminating evidence, does this rich and beautiful woman really think she can escape?!
But he didn't realize that his carefree attitude would make the aloof female professor fall completely in love with him.
……
The entire school was completely shocked when their relationship was discovered!
Lu Wang's peaceful life was completely shattered.
The "good brother" has completely dropped the pretense and transformed into the campus belle of Jiangcheng University!
The "older sister" produced a paternity test report.
Faced with the women surrounding him, Lu Wang let out a mournful cry!
"How did this world suddenly become so crazy?! Don't come any closer!"
