So some people were saying that Lynn is two-faced, but I think it's more accurate to say that Lynn BECOMES two-faced. At first, Lynn really does care about the empress. But it's when the Emperor starts catching feelings for the Empress that Lynn starts to regret pushing them together. Lynn realizes her feelings for the Emperor and becomes jealous when she sees the Emperor and Empress getting closer, from that point on, Lynn really becomes a bitch.

As for the relationship between the Emperor and the Empress: The Emperor is the Male Lead.

At some point, the Empress & Emperor finally confessed their feelings and were acting lovey dovey when suddenly there was a messenger saying concubine Lynn had an illness and the Emperor had to leave.

Then just before the ML left for Lynn’s place, the MC asked him to stay with her because she just had this feeling that something bad was going to happen. The ML still left the empress to see Lyn but Lynn was all fine, just wanted to eat something together. So the ML asked Lynn if she faked her illness and that she'd never done something like that before etc. While they were still talking and taking their sweet time together, a messenger came rushing and told the emperor that the empress was kidnapped from her place by assassins.

Then the emperor rushes to the MC’s palace, only to see everything in disarray and calls for a horse to go look for her while everyone was discouraging him saying it was dangerous. He goes after the empress and finally finds her, but she is bleeding and he was crying and shaking her body really hard repeating “Empress wake up/say something...” Somehow, he loses the MC to the assassins again (? the person who wrote the spoilers doesn't know the exact details) and he cries hard recalling the MC’s last words, which were: “can’t you stay with me because I have a bad feeling something bad is going to happen”

The MC was nowhere to be found for 2 years (presumed dead) and during that time the ML turns into tyrannical king and everyone says it is due to the death of the empress.

After the empress’ death, the MC goes back to her original body (she actually knew she had to leave the empress’ body that day so she asked the emperor to stay with her which became a huge trauma to the ML) and after two years she goes back to the palace (she looks different now, not like empress) disguised as a male escort/bodyguard due to political shenanigans. The MC was actually summoned for a reason, and it involves this radical group founded by the Ryeokuk’s royals who wants to assasinate the emperor.

MC felt somewhat attached to the group though. She enters the imperial palace and wants to protect the emperor seeing how the ML blames himself hard for everything and turned into someone completely different. The ML also left the empress’ place exactly as it was before, and gave out harsh punishments for everything involving the 'late’ empress. The story kind of turns into a ‘BL’ romance, because the ML is reminded of his one true love--the empress--because of the way the disguised MC behaves (has the same expressions/habits). ML admits his feeling for the new MC pretty early on, even though the disguised MC is a ‘male’ escort/bodyguard, because the emperor really regretted losing the empress without admitting his feelings. The ML even gets jealous saying you should be my man even in front of beautiful women lol and that causes Gong Lin to panic again and she tries the frame the MC, and even going as far as recreating the bloody ML’s trauma by harming herself and then copying the last words of the empress to hold onto the ML (which is pretty messed up imo).

MC felt angry about that incident and tried to tell the emperor the truth, asking what if the empress is not dead but just hiding herself due to circumstances...but the ML reacted pretty violently and storms out to go see his concubine. MC was disappointed because it reminded her of her last day - even when it is extremely important, he always chooses Lynn. So MC starts acting cold to the ML, refusing the snacks he orders for her, not meeting his eyes, and trying to avoid eating together etc. ML was scared that he hurt the MC, and he didn’t want to lose ‘him’ too so he asked why he was mad and he will try to fix whatever it is which surprised MC since he would have never done this before with the empress. ML even confesses that he is in an unrequited love with him in front of everyone, and tries his best.

That’s why when it was revealed MC is part of the infamous group that abducted the empress, it hurt him pretty bad as he thought she approached him on purpose and how he really fell in love with the person who killed the one he loved the most. While in prison, she tries to say she was trying to protect the emperor all along, but the ML was very conflicted with his guilt for the empress. Then when MC is alone with Hoon, she confesses her real identity considering her group obviously abandoned her and left her to die, and to prove it she recounts how they met the first time, with the intruder and the stone... The prison guard, listening to their conversation, was a member of the group, so the guard murders the MC while Hoon and the emperor were on their way to the prison. ML sees another bloody gory dead MC, a repeat of his worst nightmare, is shook to the core for the second time.

Fortunately, MC goes back to the empress’ body and a lot of political stuff about this prophecy about her and how she will rid of this group from Ryeokuk. She is given three choices including one where she goes back to her original world and forgets everything. But MC chooses to stay with the emperor and goes to the palace and meets the ML. He couldn’t believe his eyes and kept asking Hoon if he was seeing a ghost and is over the moon when the MC comes back in the empress’ body. Then she teases him saying I heard you were having an affair while I was gone and then kind of explains all the prophecy/politics to him. She couldn’t come back officially due to the threats from the group and the ML wanted to kill all the people involved in the group right away, but MC persuades him to wait to avoid shedding innocent blood and work to eliminate all the discrimination against Ryeokuk people which was the root of all this. The stubborn emperor couldn’t even believe himself that he actually listened to her and puts out an edict while she is sleeping. The book ends with the emperor kissing the sleeping MC saying I can endure everything for you (or something similar) with tears.
