Asking that question was always a bit awkward; after all, when two adults are in a relationship, it's too abrupt for him to inquire.
Finally, Fu Mingchuan expressed his concerns in a very tactful manner: "A girl should protect herself well."
After all, it's his own daughter, and even if he turns a blind eye to her not coming home at night, it doesn't mean he doesn't know.
And as she's a girl, he could only express himself in a restrained way.
Back then, he had Fu Yi before graduating from college, followed by a quick registration and a simple wedding. At that time, he was just a poor young man, and he didn't buy anything for their mother, who always endured hardships with him.
Later, when his business started to pick up, he hadn't properly compensated her when she passed away shortly after giving birth to Fu Ying.
Fu Mingchuan sighed deeply.
"Dad." Fu Ying took a moment to react, then realized what Fu Mingchuan meant by "protection."
