The acting in A Life Time Love is atrocious, lol! This is why I can’t watch very many of the older Cdramas. But, I was fascinated by the story, wanted to know more, and found translations of Once Promised (partial translation only) and its sequel Lost You Forever (full translation). The author Tong Hua is an amazing novelist. I was gripped by her storytelling and writing like never before.
The FL in Once Promised is XY’s mother (Victoria Song in A Life Time Love). The FL in Lost You Forever is XY, of course. CX is another character who is in both Once Promised and Lost You Forever. He and XY are cousins. His father is one of her mother’s older brothers (Leo Luo in A Life Time Love).
I found a partial translation of Once Promised at the following link: https://www.novelcool.com/novel/Once-Promised.html. It’s 12.1 of 17 chapters of Volume 1, and none of the 19 chapters of Volume 2. (For a translation of Lost You Forever, see the other thread.)
