Sangzhi meets Jiaxu when she was 14, and fell in love with him when she was 17 and he was 22. Jiaxu was her brother's best friend and honestly, this is the healthiest drama ever. The plot, the acting, the storyline was amazing in so many levels. Sangzhi was very personality driven, never accepted unlawful behavior from anybody. She's by far the smartest character I've seen. And damn!! her brother Sangyan was the most beautiful character to exist. He really raised the bar for brothers and best friends. And Jiaxu! damn that man is one charming man!! his efforts to win Sangzhi was just worth dying for. Conclusively, this is the best drama I've watched. Highly recommended!!
