Denting piano (Piano tinkling)

Tata stared at the ceiling of her room, now her days passed like a drama, because of Tata’s own decision to make his relationship with Key a friend, Now the four of them always go everywhere, have lunch together, go out together, study together, go to the library together, Join a music club together, looks fine, but there’s something that’s stuck in her heart, Every time Tata turned his gaze to Key, by chance Key was looking at her, Does he always look at Tata with a look like that every time? A look full of hope and regret, Key seemed to harbor deep disappointment in his heart, So every time Tata looked at him he looked like he wanted to cry. Is it better for them to act like strangers than friends? Was it so painful for Key to become friends with Tata again? 


Tata really felt touched and disturbed every time his eyes met Key's eyes. 


"have you gone to bed?" Someone pushed open the door to Tata's room, Tata suddenly sat up. 


Think for a moment...
