Fated to love you is the Taiwanese version of You're my Destiny - Marriage due to one night stand. Both are very good
Thai remake of You are my destiny is one of the modern versions, most of the things follows the original Taiwanese script.
You're My Destiny (2017) is the Thai version of the same story. It's pretty good. It follows the original Taiwan version (story wise) pretty closely, like the Korean remake. The Taiwanese and Korean versions are both called Fated to Love You. Anyway, story is similar- plain girl meets rich guy, one night stand leads to pregnancy, get married and eventually they fall in love
