Who Did You Give Your Smile To?

Real life is like an iron brush, constantly washing away our broken dreams. We change and we live strong. When trust becomes cheap and sincerity is buried deep in my heart, I know that I can't go back. Gradually, when I was burdened with various debts, I didn't know how I ended up like this. I couldn't remember how long it had been since I smiled happily. Where did our smile go? Who did you give your smile to?
