When did the emperor favor wreaths?

In Yan Xi Palace, which episode did the emperor prefer Wei Luoyu? It is understood that their first consummation was in the 43rd episode of The Story of Yan Xi Palace. In fact, Emperor Wu of the Han Dynasty tried to be nice to Wei twice before, but both of them were cleverly rejected by Wei.

In the 43rd episode of the story of the palace, Wei was sleeping and was suddenly awakened by the emperor, but when he got up, he was held in his arms by the emperor. The emperor let down his guard against Wei Ailuo, and he liked her a little, so he couldn't help but have a consummation with Wei Ailuo.
