Liu Yang only left Song Yu's house during the night. That is, he spent the entire day with her.
The two played in every perverted way possible the way couples do.
After dinner, they played some more before saying goodbye.
When he walked out of the entrance, no one stopped him, but some neighbors were talking about him going to Song Yu's apartment in the afternoon and only leaving at night.
Most of the comments were about him being Song Yu's lover or a rich young man who paid to sleep with her.
The people who talked the most about this sort of thing were the women who were envious and jealous of Song Yu's beauty and wealth. What most irritated these women was that their husbands and boyfriends always looked at Song Yu when she walked down the streets or in the hallways.
