La Mu: His shard was protected in the tree and represented the child/fear/innocence that Youqin "cut" off when he was younger. This means in a way, Yetan already met and "saved" La Mu when she was the one who said it was okay to be scared even before the shards went to human realm. Another hint was when the "small Youqin" first appeared, it didn't want to hurt Youqin and Yetan, same as La Mu who didn't want to hurt others. His baseline kindness came from Youqin but part of his strength came from Yetan who "saved" him back in the heaven realm. In a way, this makes La Mu extra special because he was the shard that existed for hundreds of years already even before Yetan arrived but he was also the shard that Yetan saved back in the heaven realm and again in the human realm.
Mei You Qing: His first scene showed him picking up a coin from poop water. Is it just because he is that greedy for money? Remember the scene where Youqin basically traded her food for all those treasures, Yetan accidentally spit on him with rice on the same location where MYQ wiped the poop water on lol. How is this related? Youqin is someone who is sensitive to people touching him/likes being clean, but at that moment, he didn't yell at Yetan and that gave birth to the feeling of "Fine, this is fine, Yetan spit out rice on me but that's fine". This adds to MYQ being someone who doesn't mind being "dirty" due that single interaction with Yetan. Another moment that also added to MYQ's existence was the scene where Youqin didn't have money to buy the bone flute Yetan wanted in their first meeting. Basically the thought of "I need to have money to buy the things my partner wants".
Wenren: The original thought is that he is the Youqin who got influenced by that fruit and just copied whatever Yetan said to Youqin at the time ("You have a nice face" and "I can't wait"). However! The main point was that Yetan said those words to Youqin BEFORE Youqin got affected by the fruit. He was clear-headed at the time so he was already feeling things with thoughts like "Oh she thinks I look nice" which he then "cut" off. So in a way, Wenren is the shard that clear-headed Youqin birthed because he was already feeling something then for Yetan and the things she was saying to him.
I love the main CP so if it is true that the producer is again pulling strings to push his own artists, I hope he stops. I hate when producers/directors/script writers get involved like this to push their own agenda. There was another drama I watched where the 2nd ML is an artist under the producer's company and the script writer really liked the actor so they kept on adding in scenes for him and ended up cutting scenes from the main CP which affected the flow of the drama. C-ent in general pushes CP shipping so if the reason is to somehow make the 2nd CP more popular, it is just going to turn people more off from them. Netizens are also not stupid so they see what is happening. There has been side CPs like Hao Du x Li Leyan (The Long Ballad) that got REALLY popular but their CP scenes didn't take away from the main CP scenes. Main CP and second CP can co-exist but people behind the scene need to stop getting involved when it leads to scene deletion and narrative changes just to push whoever they want to push.
