- When ML was dispatched to fight the enemy in the north, they encounter food shortage. MC personally sent the grains to them. When ML attacked the enemy camp and didnt return for days MC did a great job motivating the soldiers. He even played the drums on top of the wall and stayed awake wanting to fight along side with the soldiers.

-ML came back and MC was so relieved that he passed out.

- MC and ML stayed in the north border. MC's great knowledge helped build some agricultural tools. He also help in making cannon and gun. The northern border became prosperous.

- MC gave birth of twins, boy and girl. That is where they started to search for MC's origins.

- the Emperor asked them to return. When another enemy attempt to invade, ML was sent to fight. The crown prince use the opportunity to rebel. He also planned to take MC as hostage. ML and MC knew that crown prince will grab the opportunty so they make sure that ML's palace was was guarded and have enough food.

- ML was supposed to go back in 3 days so MC fought hard without sleeping. He use the gun till his hand hurts. When the gate was damaged the common people rallied to help the MC. When it was almost time for them to lose. He ask his guards to send the babies away, he is also willing to commit suicide instead of being a hostage. Thankfully ML came with the northern army.

- ML didnt crown MC as empress cause he knew MC wants to join the court not to work in the palace like a woman.

-ML accompany MC in finding the truth of his origins. The ministers are not happy but they knew that they cannot stop the emperor. On their journey, MC confessed his rebirth to ML.

- The story of MC's ancestor and their clan was so sad : (but MC found his clan.

- the extra made me cry.

MC suddenly went back to the past where pastML was grieving over his death and was about to commit suicide. He talked to pastML about the peaceful world the curentML created and stayed with ML. MC also told him about the misunderstandings they have before. MC helped him calm the court and pastML was so happy. The ML got motivated that if the other him was able to make a peaceful place for MC, he could do it too. He hope that god would let the MC stay with him. His dream was shattered when he found that others don't see MC. MC knew it all along but didn't tell pastML. The palace thought he was crazy talking to himself. One day pastML woke up and MC no longer there. He was sad but fire in his eyes burn. He vowed to protect the country even if MC no longer there. When he go to court he decided to kill the crown prince and the rebels. It took pastML 15 years to undo the damage in the country and made it prosperous. When MC woke up crying, he realize he is back. Currect ML hug him and kissed him.

- the little princess became a warrior like ML and dreamed to become a general. The little prince was an intelligent scholar and was the crown prince.

Disregarding the fact how he lost his Consort Mother, his horrible family members (maybe except for that aunt of his, probably), troubles within and outside of their kingdom, it doesn’t help that MC was that afraid of him. For ML, MC was that innocent pure sunshine in his life on that autumn morning. ML kept his promise of being the one to protect MC, no matter how many years had passed since that one time meeting in their childhood. And MC never quite understood why ML did all those things for him, simply because MC forgot having met ML in the first place. It is heartbreaking all the more when you think about how ML held unto the jade token MC treasured most when he died. Despite believing that token may have been given by MC’s true love, ML just wanted to have something of MC with him even in death while still believing MC never wanted him.

In the extras, even ML showed surprise with MC’s progress. His impression of MC remained to those scant moments of interaction which defined his MC as an introverted reclusive man who was fearful of ML. The other MC who experienced ups and downs with another ML and together ruled an empire for more than a decade showed wisdom and decisiveness, not even batting an eye in ordering the execution of traitorous ministers which his MC was not capable of.

owing to MC’s hidden identity that he knows nothing about.

the ML dies in the original timeline

• the ML going to his doctor friend to learn how to make s*x feel good for the MC due to his ahem, size~
• the reactions of the ML's soldiers to their wangfei and how he "tamed the lion"
• they go to a lantern festival and the ML secretly sneaks away to get the MC's wish lantern from the water to see if the wish is about him because he was insecure that the MC was harboring feelings for another character
• actually, the entire misunderstanding between the ML and the MC about the MC's rumored affections for his cousin is really funny both because it shows the ML's insecurities, which made him a better character, and the MC's obliviousness to romantic overtures (it was so funny when his cousin was like but you accepted my love poem?? and the MC is like... dude I was just being nice idk sh*t about poetry)
• the face slapping that happens to the MC's shitty family
• the backstory that the MC/ML actually met as children but the MC forgot due to a fever
• the ML buying desserts/food for his wangfei, so much that stores basically make the MC their mascot to sell more food to people

MC’s sister should have been one of the siblings’ teachers

ML already have crush with MC since children and decide to protect him when he grow up, but MC didn't remember meeting ML because he had fever when he was child, MC also started to have feeling for ML from the previous life when he became lingering soul watching ML living his life in pain
Slowly they fall deeper in love with each other

MC are from cursed clan that men can give birth, beside having excellent appearance, they also live longer than normal people, which made people to believe whoever eat their flesh will gain immortality, that's why they live in seclusion

Its nice that the past life will also have happy ending

Moreover, the part where MC became a wisp of soul and just watched over how the ML lived his life in utter loneliness to when he committed suicide and then on beheaded and had his body thrown was so painful to read especially from the MC's perspective. You can feel not just his sadness but also his regret, frustration, and just despair for the the ML and generally for the lost time that they could've spent happily together.

like Xue Wuyi who we know that he is dead but I really want to see a happy ending, then Qi Wei who doesn't have a partner and maybe a mermaid character named Xiao Mu Yu who helps them in the last few chapther... yes there are some characters that I wish in fanwai (extra)

MC came back to untie ML's heart knot (in chinese heart knot means unsolved problem that been keep deep down in heart) in his previous life, and after turning it into a happy memory ML recalled about his previous life, so there is no more regrets

so ML (the sad emperor) rebuilds his life of up to 15 years to the current timeline,

he (curent emperor) wakes up and remembers the story of his previous lives and with both memories unites with MC
