No matter what mindset Zhang Yujun was in not to take full advantage of Ying Xiaoya, the fact is he had ill intentions and was filthy in his methods, never caring about his reputation to achieve his goal.
"Got drunk and walked into the wrong room"? Are you kidding, a grown man staying the night at someone's place and then accidentally wandering into someone else's room? Plus, out of all the rooms, why did it have to be Ying Xiaoya's room?
In short, there's no need to say more, this is clearly a huge conspiracy. Who knows if that female colleague Guan Liyan was an accomplice?
"What did I tell you, to be more cautious. Look at you, giving your life away over alcohol. A girl drinking herself to death with others while away from home, why can't you be more careful?" Cheng Su chastised Ying Xiaoya with disappointment, as if she were upset with her for not meeting expectations.
