She didn't understand?
Mother had clearly intended to adopt Xiao Huan, but she sabotaged the plan in secret, always wanting to drive him away.
And Xiao Huan, keenly aware of her dark thoughts, wisely chose not to mention them in front of Mother and left on his own accord.
Even though she no longer harbors any feelings of dislike towards Xiao Huan and could persuade him to return, why hasn't she done so?
Because she knows that if Xiao Huan comes back to stay, she would definitely not be able to resist tainting him.
Even now, in school, where one of them is in the lower grades and the other in the upper grades.
The occasional encounters are enough for Ye Shiyu's mind to be intermittently infiltrated by those filthy thoughts.
If she could spend days and nights with Xiao Huan, the despicable her wouldn't know what she'd end up doing.
