Core clues:
1. Young Vow: The young boy Dongfang and the young girl fell in love in the countryside for the first time and made a private vow for life.
2. Sudden farewell: The day after the private vows, Dongfang enlisted in the army.
3. Imposed marriage: Before/after Dongfang left, the postman working at the small town post office made a marriage agreement with Tianyuan through both parents (especially Tianyuan's father). Pastoral strongly objected.
4. One-way watch: After Dongfang passed his recruitment period, he began to write letters to Tianyuan (which lasted about a year, dozens of letters).
5. Silent obstruction: Tianyuan never received a single letter (intercepted/destroyed by the postman working at the post office).
6. Misplaced destination: A few years later, Dongfang returned to his hometown to visit relatives and found that Tianyuan was married. Her husband was neither him nor the postman, but the silent and steady Shishan.
Character settings:
• East: The name symbolizes vitality, distance and the fate of separation. Passionate, committed and ambitious. The feelings for the countryside are sincere and warm. Enlisting in the army is a duty or a way out, leaving with a vision for the future and a commitment to the countryside. The life in the military camp sharpened his tenacity, and his heart was always filled with nostalgia and concern for the countryside.
• Pastoral: The name symbolizes country, innocence and fertile soil that carries emotions. Stubborn, opinionated, and full of inner emotions. He loves the East deeply and dares to make a private decision to resist arranged marriage for the rest of his life. Facing the postman's engagement and the "no news" from the East, he experienced a long period of pain, waiting, disappointment and even despair. The final choice is silent resistance and helpless compromise, and it is also a farewell to the past.
• Postman: The name is the profession, symbolizing the letter
