Shen Yizhou watched Song Changqing's thin back disappear at the bottom of the stairs downstairs in the apartment, and remembered what Song Changqing said before going up, you will always be my best friend----
Shen Yizhou walked out of the corridor, looked up and watched the lights at Song Changqing's house turn on, and waited quietly until the soft and yellow lights went out. He was unwilling to be just a friend, knowing that Song Changqing regarded him as a good brother who had grown up together. Shen Yizhou curled his cold fingers and rubbed the joint of his index finger with his thumb, "I will be your strongest support -----" Shen Yizhou thought almost obsessively, "until you have no one to rely on but me, only me."
