I knoowww!!! It was like what???!! 1 chapter for the night before and during the engagement??!! There's alot that's missing. I didn't type the monologue/delusions on ml while looking at himself in the mirror, while preparing for the engagement. He was totally so into Yve and justifies her actions as her "liking" him too much. So i really suggest you read the novel, so you can get the full experience.

I didn't read the whole chapters. Just 3 latest chaps and that missed out point is very wasted. That point you've shared should have been a vital and most hurtful (especially how sensitive the "pregnancy" is) to the FL and very much a call for her to leave and give up on him.
╥﹏╥
Wtf why didn't they show the scene where he said he would kill her baby? I think that was the decisive factor that made her leave him rather than katarina being pregnant.

"It's not going to happen."
"You don't know that. It can be possible."
"If that really happens, I will rip the seed that I sowed with my own hands
