I Slept With My Sister’s Best Friend, And She Is Actually My University Professor.

[Urban daily life + campus + professor + single female protagonist + sister-brother love + sweet writing] (The ratings have just been released and will increase in the future)
Xu Wang’s sky has fallen! He met a drunk woman and took her to a hotel to take care of her for the night. He turned around and discovered that she was his sister's best friend and his university professor!
Wen Yu was also confused. She slept with her best friend's brother all night, and he was still her student.
...
Wen Yu, a professor from the Lengyan Royal Sister Department, pretends to be unfamiliar with her in class. After class, she catches Xu Wang secretly glaring at her. When she is teased by the palm of his hand, her hair suddenly goes crazy. She calls her sister in public and makes her ears turn red with embarrassment.
The more she hides, the more entangled Xu Wang becomes! After deliberately flirting in class and making excuses in private, with the handle in hand, Professor Leng Yu still wants to run away?
Xu Wang: I have settled on the relationship between brother and sister. This flower of the high mountains will be my wife sooner or later!
...
A few years later, Professor Wen applied for maternity leave with her pregnant belly, and the whole school went crazy:
"Holy shit! Xu Wang married Professor Wen home?!"
"We have been single for four years at the same school, and you just took the goddess professor away?!"
