"Hm… What's the matter?" Yin Tingxue asked, slightly puzzled.
Yin Weiyin, being a few years older than this young girl and quick-witted, immediately guessed the so-called "boyfriend-girlfriend" dynamic was far more complicated than it sounded. Only this little fox would believe it so naively.
Thus, she leaned forward slightly and said softly:
"If I win, you must give up your spot as his girlfriend to me."
Yin Weiyin's voice carried a certain mysterious clarity, reminiscent of a consort in a deep palace vying for favor.
The little fox scratched her head, vaguely understanding Sister Weiyang's feelings and sympathizing with this cousin. But even if she wanted to relinquish the position, she did not dare to.
Besides, she did not want to. After becoming Chen Yi's girlfriend, he treated her much better.
Yin Tingxue tactfully declined:
"A man can have more than one girlfriend, you know."
