Lefebvre is a man who grew up in poverty, death, and violence and could only really rely on himself and his strength. But as the story starts and meets Lucienne, he realizes that he could have fun with a strange child who doesn't cry and could even pierce his bigger strength: the ability to not be seen. Adds to this the fact that everything must be under control, what's better than a girl that could even abandon her life for him? But while the story and Lucienne grow, he learns that being possessive is bad, and true love asks for compromise: set her free sometimes, let her make friends, and so on.

She gets back the will to live, to meet people, to make friends, to go to school, to think for herself. Again she is a grown woman, how did she come to be so lifeless? well add to a terrible previous life, a reincarnation where she gets tortured for weeks, it's heartbreaking to see it. But also very good because this is also the backstory of the actual villainess character in the game. The character will do evil, but at the same time, the other "good" main leads are guilty as well because they will create the villainess. This give depth to the otome game subplot and secondary characters despite not being the main story of the novel. And everything will serve to make Lucienne grow knowing the previous timeline

Yes, basically from volumes 2 to 4 Lefebvre will never look and Lucienne's body, will never touch her, and will also point a blade at his boss for suggesting that. This is important to understand because the early Lefebvre isn't there for segs or love, is there for the amusement and obsession of total control over a human life, and if he fails in managing it... he will kill Lucienne because she doesn't matter, yet. The whole story answers to that. and being NO depiction of Lucienne's body, No depiction of intimacy, NO depiction of physical love (but the one that steams out from the mentally insane way of thinking they both have), if you focus your reading on that point alone... well, it's worrisome

Once the school arc is finished, and Lucienne has finished growing, she must leave society or die because she carries the old royal family blood. This is set from volume 1, she will go away from the capital and will live with Lefebvre now finally free from every social obligation and finally free to show off their love (in like 15 years together they kissed a couple of times and nothing more). The story from this point will follow their honeymoon which will take place in volume 5. Well, yeah, it's not a Korean novel, it won't go in THAT direction lol

His aim is to keep Lucienne as isolated as possible from the outside world. She should rely on him completely, grow attached to him, and lose interest in the outside world
