What a serious disappointment. This started off great, but after 20 episodes or so began to use the same tropes over and over again....like MULTIPLE times. Needless to say, it was super repetitive. There was a grandmother with dementia whose dementia episodes were hilarious, but got old real fast. The female lead was an absolute doormat. And don't get me started on the antagonists. These women were shameless and hypocritical. They showed no remorse whatsoever. I don't even think they learned their lesson. I kept waiting for karma to hit them like a bus, but it did not happen sadly...or at least not to the extent that I wanted. The secondary couple gave me life though. I loved them way better than the main couple and they are probably the main reason I kept watching. I have a higher standard for weekend family dramas, but My Only One seems like it was a daily soap that was slightly altered to fit the weekend drama time slot. With the way it was written, it is more suited as a daytime daily drama.
