The beginning of a sentimental romance novel would usually start with describing the protagonist's emotions so that the reader could feel the pain and struggle in the protagonist's heart. The following was a possible beginning: chapter one Sunny afternoon Su Linlin sat alone on the balcony looking at the distant scenery, but her heart was filled with sadness. She had already forgotten how long it had been since she sat quietly like this, how long it had been since she had felt so lonely. She remembered that it was her first day in university. She came to this strange place with a heart full of hope, met her future husband, and experienced a wonderful time. However, everything was so short and unpredictable. Now, she was back in this familiar yet unfamiliar place, back in the room that was once familiar but no longer familiar. She looked at the key in her hand and felt helpless. She remembered that it was the first day she and her husband fell in love. They walked around the campus and looked into each other's eyes, their hearts filled with happiness and love. They planned for the future, and they planned to walk through every beautiful day together. However, everything was so beautiful, everything was so perfect, but it was so short. Now, she looked at the key in her hand again, and her heart was filled with pain and sorrow. She thought of the past, of those beautiful but short times. She understood that time had gone far and they had already left this world, but she was still struggling here alone.
