Lin Shu was a bad girl, to be precise, five years ago. When an unaccustomed habit becomes a habit, you no longer pay attention to the process. If it hadn't been for what happened five years ago, Lin Shu might not have changed his gender in this life. Nor would I meet that man and the little girl. The man who shone like a star illuminated the rest of her life that she had given up on. Stepping out of that love, for her, was as hot as fire. What does fire feel like? It's a complex mixture of pain, sadness and fading memories. Holding my son's hand and growing old together with my son, at most, I can only stay with you.
