In the Thai movie "First Love This Small Matter", the female lead became beautiful and changed to another person?

My answer may not be accurate enough. The first love was a small matter in a Thai movie. The female lead, Senior Ah Liang (Mario Puzo Mario), was originally set as an ordinary student. Later, because of an accidental incident, her fate changed and she became an outstanding musician. In the later stages of the movie, the beauty of the female lead, Senior Ah Liang, improved and her image and character changed greatly. Therefore, in the later stages of the movie, the role of the female lead, Senior Ah Liang, was played by different actors. I hope my answer can help you.
