If she hadn't mistaken, he was still getting along famously with her fourth sister two or three months ago.
She and Gu Qibao even assumed he might compete with the eldest brother for fourth sister.
How did the style suddenly change, and it became her?
So, she simply couldn't understand him.
No, or rather, it wasn't that she couldn't understand, but her intuition told her that Nangong Jin was just playing around.
He was probably just bored out of his mind, teasing girls for fun, never really liking her or intending to court her.
If it really came down to it, the only possibility was that he reached the age where he wanted a girlfriend, or maybe wanted a wife.
Whoever that person might be didn't matter, it could be her, or it could be her fourth sister, as long as he found her pleasing to the eye.
Another possibility was that he probably thought his charm was irresistible, hence why he provoked her fourth sister and then her.
