I'm starting to wish they didn't fight for love. I could have done without their whole love story. It was so many missing elements. 20 episodes too long. Sorry. I ended up dropping it around 36 or 37. I didn't care if they got together at the end.
I saw the preview for 29, but there were no captions; I got the gist. Correct me if I'm wrong, but she claimed to be the child's mother. So she claims him because of the circumstances, and she genuinely cares for him. I'm guessing. She is his "Step-mom."
I went back and watched this for a second time, forgetting that it ended poorly in my opinion. This is not a spoiler. You may like the ending that went off course. Why did I re-watch it? I need to make a note to myself. AND it was SO good!
