Sweet Sister Reborn after Switch

Half-Summer died at the age of five, but was reborn. The first thing she did after her rebirth was to find her biological family, the family of Dr. Gu, who had returned from overseas. She discovered that she was not the child of her current parents, but rather the biological daughter of Dr. Gu, who was mistakenly switched at birth. She also found out that she had not only a very capable father but also three amazing brothers, each with outstanding accomplishments in the fields of medicine, technology, and the military. However, because of her existence, her parents and three brothers would blame each other and eventually become estranged, leading to a tragedy. … Dr. Gu and his wife had three sons in a row, but due to their old age and desire for a daughter, they finally had a daughter and cherished her dearly. Unfortunately, their daughter died in an accident when she was only one year old, which caused the couple to become estranged. The wife went to another country, and the three sons left one after another. In the end, Dr. Gu was the only one left to fight for his country. Then, one day, a chubby little girl appeared in his office and claimed to be his daughter. So, the mother returned with her career in biology! The eldest brother returned with his medical thesis! The second brother returned with his newly developed technology product! The third brother was even more amazing; he joined the military directly because Half-Summer said, “I like my brother in uniform the most!” PS: Chapters 30-40 were extensively revised, adding about 20,000 words.
