The more I've read the novel for the perks of being an S class transmigrator, the more i fully understand where your coming from. The adaptation is pretty much all fluff and comedy, but the novel is much much darker. It really is all in the inner monologues and little details that can be difficult to balance while meeting deadlines.

Ah, I read that as a manwha. I'll make sure to read the novel then. I thought it was a decent manwha, but hearing you mention S-class transmigrator like that has made me excited.
Also, honestly I have been seeing that pattern with manwhas. Although this adaptation is everywhere, it's more lighthearted, and it's the same thing with the manwha adaptation of the Monsterous Duke. Not to say that it's bad, but it's not exactly I've been sucked into many manwhas in which it starts off fluffy and I end up reading it to it's limits. However, it's not exactly staying true to image the author made. It's quite unfortunate that manwha artists have to have such crunching deadlines because I think with the proper amount of care put into this manwha we could have quality similar to Stepmother Marchen or that's what I had hoped.
I read this as a novel and the novel is significantly better in a lot of regards.
First of all, it's better in pacing which honestly it's not that much of a high bar to surpass. However, there was consistency from one plot point to the next
Second, internal dialogue. This manwha has little if any internal dialogue. In the novel, it had a ton of inner dialogue to show the thoughts and feelings of the FL. In fact, I loved it because it showed how much distain she had for her son-in-law and her own concerns for the other one etc. It's so so good.
Thirdly, Reading the novel, it felt like the FL was playing chess and not really fully opening her heart for the Duke or anyone except the younger son-in-law. Every action she did felt intentional and calculated. This manwha is like. Idk idk what this is.
Fourth, details. The novel was so much more detailed in telling how the FL sees the people around her in a more intimate way. How she looks at an action, how she saw the Duke based off of her own precious knowledge, etc.
Fifth, how they portray the FL is more villainess and
antagonizing and sinister. I remember the scene in which the guy threw his sword at her while riding her horse. He was aiming for the horse but the simple thought of him harming HER horse made her feel such malice towards him. How she maneuver herself to gracefully kick the sword from piercing her horse, how immediately afterwards she told her maid to throw his sword into a "Shit Bucket", word for word, SHIT BUCKET. And it really focused on her and her maid talking about the sword being in a shit bucket like it's great. She's so much more of a character in the novel. Like what happened to my girl (╥﹏╥). There are so many times in which scenes that characterize her so much are just cut out entirely like bruh.
Believe me when I say, this manwha maybe ehhhhh, but the novel is great and I suggest if you like the premise of the title to read the web novel heavily. I read this novel back when mangago was down for like a month (that was years ago) and I had to find another way of entertaining myself. I found this novel with the most interesting title and I ate it up. This THIS NOVEL is one of the most entertaining novels I've read during that time next to the Stationary Store one and Monstrous Duke.
It's just rather unfortunate this adaptation is everywhere. I want to know what went wrong during the adaptation because honestly it has so much potential, it's just that they couldn't pull through somewhere along the line.
