Dear, according to the girl," I'm afraid that my willfulness will hurt you." Simply put, she had a certain understanding of her own willfulness and was worried that her actions might hurt you. Perhaps she realized that she was too willful at times and the things she did would make you unhappy, or she didn't have enough control over her emotions and might be impulsive at times. However, the girl's words also showed her concern and care for you. She hoped that you could understand her and tolerate some of her small problems. I suggest that you communicate well and discuss how to better deal with each other's problems. I believe that your relationship will be more stable and beautiful. I hope my answer will be helpful. If you need to recommend novels, I have prepared the following for you: " Only You Will Like It The More You Read "," Flash Marriage: Don't Come Husband ", and " Picking Up a Bamboo Horse to Bring Home ". The above is my personal recommendation. I hope you like my recommendation.
