Song Yinyin quickly followed, carefully keeping a certain distance from Chi Wen.
Chi Wen didn't stay long in the piano room management office, and after handing over the materials to the administrator, she left.
Afraid of being discovered, Song Yinyin immediately turned around and hid inside an abandoned old piano room at this end of the corridor.
Just as she hid inside, Chi Wen walked past the door of the old piano room in her high heels.
But after a few steps, the footsteps suddenly paused.
Thinking she had been discovered, Song Yinyin's heart leaped into her throat.
Instinctively, she pressed her hands against the doorknob, worried that Chi Wen might come over at any moment to push open the door.
But Chi Wen did not come over. Instead, she looked up towards another piano room ahead and then walked in.
That piano room wasn't large, less than ten square meters, with an old piano inside.
Although the piano was old, its sound was full and bright.
