MC is an ancient person who somehow transmigrated to the modern world. With her accumulated skills as a trusted eunuch for the emperor, she was able to somehow pretend to be the person she's assuming the identity of. Slowly, she tries to integrate herself with modern society, being married, and having her own career.

As for ML, he is a mature, experienced, and calm person. Or so he wanted to be. In fact, he's just someone who likes to pretend (as we all do) to be someone cool. As he started to fall in love with MC, his mask fell off one by one to show his childishness and pe*vertedness in front of MC. Overall, he's a very understanding and sweet ML to MC.

The novel plot mainly tells about how suitable and matching the couple are, as they both have a thorough understanding of their own spouse and constant similar ideas on how to deal with things. As for the relations of the plot with the title, it can be played from both MC and ML side. MC's "sickness" is her awkwardness at trying to accept that her husband have the same face as her master in the previous life. For ML, his "sickness" is trying to woo his wife who doesn't seem to have feelings for him. Cue trying for more skinship and failed attempts being romantic.

at first MC felt awkward because ML has the exact same face with her master aka the previous emperor of her last life, so she unconsciously distanced herself emotionally from ML while ML was slowly falling in love with her. MC busied herself with the job ML gave her at the company and ML tried to insert himself slowly in her daily activities, notably when he asked MC to let him join her to do charity work in rural area, where then they suffered together lmao.

At some point, the extend of ml's courting made her contemplate her actions toward him, and she reminded herself that despite having the same face, ML is vastly different from her previous master in terms of personality and she didn't need to mind her actions, so she decided to act like her true self and tried to accept ML as her husband of this life. From then on everyday was spring for ML lol, even though there's a brief conflict between this couple because of ml's jealousy and mc's somewhat unthoughtful act, but it was wonderfully resolved, and that's what made MC realize that she liked ML more that she thought.

ML was soooo considerate of MC even when he wasn't in love with her yet. And when he did, he sometimes acted like a teenager in love (even ML himself thought so too lmao) even though he actually had multiple experience in dating. Ml's road of courting MC made me swoon although he failed sometimes, and that was one of the things I enjoyed when reading this novel. One time he asked MC to retrieve something (i think a water bottle I forgot) from the car trunk-- where he put a flower bouquet to surprise mc-- but MC saw through his plot because she watched romance drama where the actor did the same to the actress, so she told him to get it himself lmao ML knew the surprise failed so he picked the bouquet from the trunk and gave to her, and MC accepted it reluctantly😂

And mc!!! How I love her.. I really love how she handle people from her work colleagues to her in-laws, and she worked hard because she knew she wouldn't survive in this modern world if she didn't. Her thought process when interacting with ML and other characters made me applaud for mental intelligence, and her character development is palpable throughout the story.

i felt a little bad for the ml's cousin because she didn't think everything she did was wrong, and her bad personality is resulted by her mother's actions and lack of affection: ((

Me reading the first 2 chapters: I really hate moms who uphold the patriarchy.... I just hate the patriarchy. Sorry not sorry. But I'm tired of hearing b*tching about a women who got married and has to stay in her new home properly waiting for her new husband to come back or else god forbid ruining the families' reputation. Whatever rich families. Idc. get over it. She has feet -- god forbid she use them /rant.

so one review is saying all these inconsistencies that I'm not really seeing???:

- she was a female eunuch (yea I accept this one but it's fiction baby) and how that even happened is ridiculous

- she's more feminist than others despite coming from ancient china (fair point but also.. kinda not bc u have to remember people are not monoliths; you only have the rights u have today bc several people in time periods when it was impossible, fought to have them aka even if ppl never said it aloud, there existed ppl in the past who could have had different thinking from their time period. Rare probably but highly possible.)

- that she magically know how to do all the technology and texting so easily (... I mean no. The writing is not that great but it mentions that off camera of this novel, she had spent several days getting used to her phone and appliances before the 1st ch. And later, it distinctly will write oh yea she doesn't know a computer, car, texting, and will have multiple times where it is written she is still learning.)

- for the finance thing, it is bad writing but the explanation is still there. It is brief but existant. It said she had like a memory of how to do it as she was learning to do it so it helped her to learn it quickly -- this is probably referencing how her mind naturally remembers this from her college studies even though she doesn't explicitly have any memories from the past owner. I mean first of all u are reading a transmigration novel, are u looking for a realistic explanation? I mean as far as it goes this explanation makes enough sense for me. It's a lazy way out yes, but plausible and thus acceptable imo.

Moral of the story, I did not see what they were talking about and thus, this gives credit to reading things for yourself bc sometimes people are not reading it carefully enough. I mean disclaimer I mtled but I still got the novel more. But maybe I'm wrong.

ML kept all the love letters he received from his childhood to show off infront of MC.

he also tells that he would have been picked up by an agent in music industry if not for him being rich
