I often think of the night I first went out to U, the starry sky was so bright, the light from my phone screen illuminated my greedy face. I couldn't wait to transfer U to the U merchant, eagerly waiting for him to release the funds. At that time, I would never have believed that I would lose so completely. The greatest sorrow in life is never failure, but rather the realization that comes too late. Now, the ones I feel most sorry for are still my family.
