Dr Ghost

He never loved SRQ and was with her cuz she was supporting nobel families and his brother son to ascend the throne.

He knew for a fact and it was SRQ, who forced LC to poison her to death in the first place to place su family member on the throne. Not only he knew what she was poisoned with him, he himself fed the last dose and he and Shagguan Ya watch her die.
They had the antidote and everything on them !

In the bath scene were the ML is scene talking to his other self, he clearly shown mentioning that in the past life LR was his wife and SRQ was an eunuch that's why they could only snuggle at night (sleep together) and couldn't go any further to have child or family but in this life SRQ has everything and he needs to be more active to pursue LR otherwise he would loose her completely in this life.

This will be scene that will collaborate with the chap, I mentioned above !

It has already happened, and this (above mentioned chapter) was the snuggling he was talking about, stop lying to yourself and the public !

any news of express package?

So, its not like he didn't tried to apologize or explain the situation to her. She never gave him chance to explain himself, when he did ignore it.

Then after this scene and some years, his mother died and he as crying like mad man and was very sad, FL come to perform his duties as wife (send of his mother) with SRQ, he not only apologized and explained the whole Qin Zhen Zhen ordeal (he don't love her and was only saving her).
He properly begged by putting his hands on her legs and feet, while crying for forgiveness but SQR said her highness its time (after listening to ML begging and fearing it may hurt his plan), she literally forcefully removed his hand from legs by kicking and went on to sleep with SQR again (she hurt him even at his mother death).
These things have already happened in drama, so I might as tell you. Why we hate her to much and consider it insult to man, that he chasing her again and putting up with shit.
I am just telling you two events, there are alot more in the novel and you will see, whole boat ordeal.

Here is it and it was referred in novel properly, but drama skimmed over it,
Dong Ye looked at Pei Wenxuan's appearance and finally persuaded him, "Go back to the princess's residence. You are the prince consort after all. No one can stop you from going back. Su Yongqing is a eunuch. He can't do anything. Go back, apologize to Her Highness, and live a good life."
Apologize and live a good life, Admit your mistake and admit defeat and as long as you admit it, she might turn back.
He stood on the long street. For the first time, he wanted to turn back. He wanted to go back and take back everything that belonged to him. When he came back to his senses, he ran all the way back to the princess's residence and knocked on the door.
When the gatekeeper saw him, he was stunned, "Prince consort?"
Pei Wenxuan didn't say anything. He pushed the door open and was about to enter. The gatekeeper reacted and hurriedly said, "Prince consort, please wait a moment. I will go and report.
"Report what?" Pei Wenxuan was angered by this sentence, "This is my home. I want to come back and find my wife. Do you still need to report?! Stop right there!"
Pei Wenxuan shouted loudly. The guards rushed in and stopped the people from the princess's residence.
Pei Wenxuan rushed all the way. He thought about it. He and Li Rong would apologize, he and Li Rong would admit defeat, he and Li Rong...
However, all his fantasies stopped when he heard Li Rong's light breathing.
He stopped in front of the door and listened to the voice inside. He couldn't be more familiar with that voice.
But this time, Li Rong didn't call his name. She called Su Yongqing.
She said, "Rong Qing, hurry up. Be gentle."
He wanted to go in.
He wanted to kill Su Yongqing.
He had never wanted to kill someone so much.
He should have thought of it earlier, but...
He didn't dare to think about it.
Even if he was a eunuch, as long as they were in love, there would always be a way.
But what did he have?
What status did he have?
He stood at the door and listened to Li Rong and Su Yongqing's voices. After a long time, he finally turned around.
He seemed to have suddenly sobered up and left dejectedly.
He walked on the road in a daze. After walking for a long time, he clearly realized that Li Rong had left. She had left their world. She had found someone new. She had truly, completely, let go of everything.
This realization made him feel as if a fishbone was stuck in his throat. He couldn't help but remember that an official had invited him to a banquet tonight.

I can't un-read this shit from my mind and forgive FL, ever !

The point I am trying to make is, drama has not changed anything from novel but instead they have removed leads sex scenes/romance, which writer used to balance the hate and make it bearable.

It has not deviated at all, and all major details are there. She will be empress, but drama is going through chapters at super-sonic speed and in doing so, they are skimming over important facts/ character progression points.
Let me give you an example of this behaviour, (Did you remember this scene)

In the bath scene were the ML is scene talking to his other self, he clearly shown mentioning that in the past life LR was his wife and SRQ was an eunuch that's why they could only snuggle at night (sleep together) and couldn't go any further to have child or family but in this life SRQ has everything and he needs to be more active to pursue LR otherwise he would loose her completely in this life.

Now I will give you context from novel, what event ML (proving she cheated) from the past was referring to by "Snuggle at night". It was in chp 170 and one of reason, I hate FL character that much,

I know this and even after that, her treatment of ML was not any better. So, that's why I am waiting for all these "Nay sayers" to come up with excuses to justify her behaviour. This is the sole reason, I have not dropped this shit cuz I want to hear the dumb excuses !
There is nothing wrong in accepting your mistakes !

Okay then where is ML harem !

Yes but he indirectly killed her (he didn't poison her himself but was directly responsible for poisoning) and knowing very well, she was poisoned didn't tried to save her. I hope they dwell in past bit more cuz things were way more complicated than drama is showing.....apart from ML, everybody (by everybody I mean everybody) else in her life betrayed her!

Lol, Ladies didn't had harem back then and there were two women at max, who had lovers and one of them was Empress Wu and thanks to her lovers. It didn't end well for her !

They will hint at this scene it in upcoming episode !

Let me give you a little spoiler, him attempting to murder ML second time and FL barely saving ML didn't change much for ML.

Lol, accountability in female empowering drama. Even if I had not read the novel it was not going to happen till the other option has become completely unavailable.

Well in that case, prepare the tissue box and stay away from my review or last narration of story comment.

One word, let see till the end of the drama. How much character development she would have....

Its not split down the middle and overwhelming majority is in one side but like I said, they went too far and her behaviour/crimes in previous life are unforgivable.
If it was Xianxia or any other fictional story, I wouldn't have give a "F" if FL humped half the known galaxy, while being married to ML or she was sleeping half of the Sith race/dark force users.... but its supposed to be based on real life in ancient china and they are portraying humans (not aliens).
No living man is going to overlook or forgive "infidelity, emotional torture and then murder (under cheaters persuasion)". To top that off, her motive or reasoning behind doing all that is very weak. He saved his ex-fiancé from certain death and then handed her over to her husband. he wasn't cheating or sleeping !

I am happy someone recognizes the root of the problem and is willing to state the hard/cold facts as they are, these very successful, ultra virgin type of ML are the scourge of c-dramas. I have seen quiet of few c-dramas and usually ignore character like this and never reacted to shit like this, but this time they went far far to extreme.
We are talking open cheating with live broadcast to entire capital, she picked a eunuch over Ml and is sleeping wither her, mental and emotional torture and when she can't torture him anymore....she killed him !
Now in second life, it was ALLL ML fault and now victim is chasing the aggressor...like there is limit to everything and I have 140 c-dramas so far but its the first time. It feels like entire premise of the story was to insult the other gender and I know its fictional story but no man in the world, is going to put up with that much.
