Zhao Jia.
When was the last time Lin Zhu interacted with the long-haired girl? The last time was probably when Ye Quan forced him to cover up his date with that girl in the cinema, right?
At that time, Lin Zhu was still recovering after he was sent to the hospital the night before, but both Ye Quan and Zhao Jia were very selfish, and they even took him with them when they went out on a date just because they wanted him to protect their relationship.
At that time, Lin Zhu felt that he was done with everything, and that was why he left the cinema before the movie was even finished. He had decided to leave Ye Quan's life back then, and that was why he had even moved out of Ye Quan's house.
That was indeed the last time Lin Zhu interacted with Zhao Jia. In the past few weeks, he had still seen how the girl joined team training and also participated in tournaments, but they didn't interact at all.
