the actual story is more complex she doesn't just bow down and nod her head and as for the male lead in the book he doesn't simply accept the baby he goes through a period of not wanting anything to do with the baby out of fear
Do you mean this article

it looks the same half of it.
Read the actual book it goes into much more details and she did what she had to do to help in securing a better future for her child just look at how both mentally and physically tough her job was plus doing overtime while pregnant car breaking down so no way to go to work sure their are ways she could have did it on her own but it's not like it was guaranteed either way
I was hoping to be on her own n raised that child.but it's like he can come fuck her.then behaving like all mighty then want to marry her.allways according his wish.she just a poor trash nodding her head according to his wish.trash manhwa though.
