Xue Feifei still wanted to struggle, but even though Yu Sixing had indeed fallen asleep by now, he wasn't forcefully restraining her. However, his arms and legs had been resting on her before, and the weight of a man's body is still quite considerable. She felt somewhat suffocated under his pressure.
Though she still harbored some doubts about him, first, she couldn't break free on her own, and second, even if Yu Sixing wasn't the best of people, he was reliable in his words. At least he had never broken a promise. Xue Feifei tried again to free herself but couldn't, so she had no choice but to stay on guard.
When she woke up the next day, Yu Sixing had already gotten out of bed and was not around anymore.
