Oh the OST. I must check them out then. Yes, the ex is absolutely annoying me with his overbearing behaviour when they are alone and then the rudeness when others especially his ex are watching. And if he forcefully hugs her, that is just too much. What a colossal jerk! Hope his fiance drops him like a hot potato and apologises to Qin Shi.
It was on wetv's official youtube channel. The videos that say trailer and the title says Ep22, Ep 23, Ep 24, etc. You'll recognise the show from the actors. The channel has English subs. https://www.youtube.com/@WeTVTaiwanOfficial/videos
May be I misread a comment that said the ex grabbed Qin Shi's hand and something happened at the wedding with the ex but the promos I saw had none of that. Worst thing I saw was the ex's gf takes over QS's office and makes her into a subordinate. Yes, it's bad of her but I found that twist exciting. May be because I find most of the people at her firm fake and they are finally showing their real faces.
After knowing what Tao and his family did to her, he was just furious.
During the meeting with her parents, she told her mom about how his mom rejected her because of her father's divorce and called her a leech and he never defended her. Yang Hua didn't know about the details of their break up before that so when he saw her Qin Shi's ex his anger got the better of him.
