Becoming Sworn Brothers and Sisters: but Can't Escape the Seven-Year Itch of Friendship

Because they were envious of other girls being cared for by their brothers, and coincidentally, the other girl longed for a sister, the two swore a sworn sworn vow, "I don't want to be born in the same year, the same month, and the same day, but just want to enjoy happiness together." The one born on October 30, 1985 was the brother, and the one born on January 4, 1986 was the sister. From then on, they started a seven-year bond. During the seven years, there was the warmth of helping each other, the liveliness of laughter, and the ups and downs of conflicts and reconciliation. After the brother had a sister-in-law, the three of them also preserved many warm and beautiful moments together. I thought that this friendship could span the years, but instead In the seventh year, the contradiction resurfaced again. The seven-year itch was not applied to love, but to friendship. This time, it could not be overcome. A connection that began with longing for family and was thought to be as solid as a rock finally ended in a different way under the wash of time. .
