Introduce the content of the Thai film "Love on the Journey", in more detail...

Nuth (the heroine) was called back to Thailand because of the need to disclose Annop's will (father who died suddenly). The new wife hurriedly held the funeral and sold Nuth's father's house. Nuth had only one inheritance left, which was his father's pet dog Handu. When she was about to find the whereabouts of the will, she was blocked, bullied and almost died. But he knew the truth. The manipulators behind the scenes were stepmothers Jitree and Sitsak. Pattavee (male protagonist) is a young photographer, but he often quarrels with Nuanjan’s mother and Paweena’s sister because of his relationship with sexy actress Jane (second female protagonist). Stepmother Jitree's sisters Nuanjan and Paweena believe that Jane is only dating for money, so they work hard to bring the male protagonist and Patcha together. After the male protagonist found out, he tried every means to avoid it. When the second heroine learned that she was going to sell the house, she suggested that the hero buy it so that it could be used as a new house. The hero's mother arranged for Oog to go to the new home to take care of the hero and destroy the relationship between the heroine and the hero. On the other hand, the heroine was being hunted, so she disguised herself as a boy and came to her father's house again, knowing that her stepmother had sold the house to the hero. In the end, the heroine managed to live in the old house successfully, using the pseudonym Anucha or Oot. The male protagonist arranges for Oot to replace the assistant who encountered a car accident. The heroine and the dog searched for the will together, and finally learned the truth. It turned out that the real will was hidden in the portrait of her father, but she didn't know which painting it was, so the heroine's task was to find the painting, and her senior brother also helped. Tan, the senior brother is the only person the heroine can trust and he also knows about the heroine pretending to be a boy. The male protagonist and the female protagonist get closer and closer, and gradually develop subtle feelings for the female protagonist. He began to suspect that he had become GAY. The hero was so distressed that he went to see a psychiatrist. Coupled with the forced marriage of the second female lead, the male protagonist decided to marry the second female lead amid the opposition of his mother and sister. The heroine, who had a crush on the hero, was very sad and immediately packed up her gifts and prepared to leave the hero's home. Before leaving, the heroine sneaked into the hero's office to steal a painting, but was caught. The heroine lied and said she was hired by Nuth to find the will. The hero believed her and offered to help find the will. But suddenly all the portraits were stolen by the stepmother and prepared to be burned, but the two of them recovered all the portraits. After going through many hardships together, the male protagonist is convinced that he has fallen in love with the female protagonist and decides to break up with her. The second female lead was furious and wanted someone to kill the female lead.
