I don't remember much since I was so young, and I didn't see the ending then either. I saw the Hmong subbed version. It's about a couple who were going to get married. One night she finds out that her fiancé has been cheating on her, so she drives into the night and cries, while letting out all the surprise balloons and all. Since she was crying and distracted, she gets into an accident. Somehow, her soul gets switched with a young girl from another family. I think she falls in love with a guy who lives in the house, but she's still stuck in the little girl's body. If anyone knows which lakorn I'm talking about, please let me know. Thank you!
