After dropping Xu Jian off, Ye Shuang returned to her parent's home, not her own apartment. Due to the fact that he had failed too many subjects at school, Little Brother Ye was now banned from staying at Ye Shuang's place. When he was staying at the university dormitory, it had been doing better. Even though there were instances of him skipping out of the dormitory at night to soak himself at the internet café with his dormitory mates, at least his actions were limited somehow. However, when Little Brother Ye stayed at Ye Shuang's apartment, he was like an uncaged bird, completely oblivious to the meaning of the word 'limitation'.
Therefore, Father Ye's stance was very clear. "You are allowed to go visit your sister but not allowed to stay overnight there. If you dare to do that, and are exposed, we'll break both of your legs."
