No "misunderstanding" the ML in this case is garbage and was a fuckboy.
He didn't give two shits about the FL when he knocked her up and their fling meant little to him. That's why there is zero chemistry and the romance feels unauthentic and forced.
As usual the weak pushover FL still "forgives" him and the decent alternative gets friendzoned.

Is so sleazy and a utter worthless pos
He is using her like a fool so he can have sex with other women. The more she
gives into to his way and idiotically lets herself be manipulated by her pos husband into thinking that her fucking other men will "help" her husband be attracted her, the less I feel bad for her.
The "friend" now has awakened another cuckold husband by turning to swapping in desperation to save another doomed relationship.
All the men in this are scum and the women pathetic.
Original story + gorgeous art.
