Did Su Manyin and Lin Haoyang have a relationship in "Angel Wings"? How did it happen?

In the eighth episode, the night before Manyin and Yunxiang were going to get married, Su's company held an anniversary party. Manyin invited Haoyang to attend the party. At the party, Caini wanted to marry Manyin. He got drunk and kidnapped Manyin so that she could not attend the wedding the next day. Unexpectedly, the kidnappers kidnapped the wrong Caini, so Manyin drunkenly ran to Yunxiang and passed out at the door of a guest room; Yunxiang felt very uncomfortable when he saw Haoyang appearing at the celebration party, so he invited Haoyang to have a drink together to see who was better. As a result, both of them were drunk. At this time, Haoyang's brother (Wu Weixiong) saw that Haoyang was too drunk. When he was drunk, he opened a room for him and asked Haoyang to rest. Just like that, when Haoyang went to the room, he saw Manyin lying drunk on the floor and kindly helped her back to the room to let her rest. Then entering the room, Manyin mistook Haoyang for Yunxiang, and had a relationship with Haoyang.
