Okay, so I finally plowed through to the end of that one after seeing it all over social media. The book is 'The Unwanted Bride', right? The ending is pretty much what you'd expect from that kind of arranged marriage trope—they end up together, of course. But the journey there is a bit messy. If I recall, the female lead, after putting up with all his coldness and the whole 'I married you out of duty' routine, finally decides she's had enough and leaves. She doesn't just mope; she goes off and builds her own life, which I appreciated.
It forces the male lead to actually confront his feelings instead of just taking her for granted. The climax usually involves some grand gesture or a crisis where he has to prove he's changed. In this case, I think there was a business threat or a family scandal that made him realize how much he relied on her, not just as a wife but as a partner. They have a big confrontation where all the pent-up hurt comes out, and he has to do the emotional labor for once.
They reconcile, but the book tries to show it's on more equal footing. She doesn't just forgive him instantly; he has to earn back her trust. The last chapter probably has a time jump showing them actually happy, maybe with a kid on the way or something. It’s a satisfying, if predictable, wrap-up for readers who want that guaranteed happy-ever-after after all the angst. I remember feeling like the final conflict was resolved a bit too neatly, but that’s the genre for you.
