Dietrich is on the cover art
Dietrich is in the promo chapter for the novel that is categorized as "romance"
Dietrich's character is heavily focused on and is not a blood related sibling to FL
People: *sees the word siblings* Okay so who's the ML?
Just because they are "siblings" doesn't mean he can't be the ML guys. This is literally like any other manhwa, if he wasn't classified as a sibling in the first place, ya'll would have no problem identifying or making an educated guess on who the ML is. Maybe bc I know that Dietrich is the actual ML and I've seen so many of these tropes it's easy for me to put 2 and 2 together. But for those who aren't able to tell, 9/10 times if it's a novel (esp if it’s Korean) with a romance genre , heavily emphasised with a convoluted explanation that they are not blood related siblings, then it's going to end up going towards an uncomfortable plot 9/10 times. An author wouldn’t take the time to explain and put those details there, especially in a romance novel, if something wasn't going to happen later. I get that it can be uncomfortable, and am not trying to invalidate on other people's opinions, but I'm just trying to say that these tropes are indeed possible and there's a ton of clues that can lead you to my conclusion.
