She is cold and independent, like a clear and deep pool. She is warm and bright, like a sunny day. They were strangers to each other and got connected online due to a tragedy. The two girls encouraged each other. They saw each other's true side and deeply realized that both of them were thinking about each other. They cherished each other and integrated into each other's lives to accompany each other. The two parallel lines began to intersect, and they had a different kind of loneliness. Deep in the soul, only the other person can heal, and neither misunderstanding nor separation can stop it. Gradually, I realize that the other person is the most important person who can heal me.
