Chen An, upon thinking of something, quickly sorted through his thoughts in his head, and finally decided on a rather vague issue regarding Sister Juan.
Logically speaking, a woman with conditions as favorable as Sister Juan's would not lack attentive company. If one were to attend a party, it would be better to seek professional servers who are even more attentive than Chen An. If Sister Juan specifically required Chen An's services, then likely, it would involve more intimate matters.
But if he openly voiced all of his thoughts, it might anger Sister Juan because, in Chen An's view, if his misconceptions led to a rift between them, causing Sister Juan to think he was not an honest man, then the loss would outweigh the gain, especially since Sister Juan had already allowed him to get close to both her and Wu Xue.
If Chen An still dared to think of other women after gaining the affections of this mother-daughter pair, then it would be quite unjustifiable on Sister Juan's part.
