He remembered that sunny afternoon—
"Yangyang, what are you doing?"
He watched as Sheng Yang's fingers lightly tapped on the table. It seemed like she was playing some sort of instrument, but it wasn't exactly the same as no instrument was played like that.
Sheng Yang raised her head. Her youthful face was still tender, but her gaze was extremely serious. "I'm forming a code."
"A code? Like the Morse code?" Sheng Hanjing gave a half-smile, thinking that his sister was really too awesome.
"Yeah." Sheng Yang thought for a moment. "This code has something to do with music."
"Yangyang, can you teach me?" Sheng Hanjing suddenly became interested.
"Sure." Sheng Yang didn't hesitate. Her second brother studied music, so he would definitely be able to quickly pick it up.
Sheng Hanjing accepted Yangyang's trusting gaze and rolled up his sleeves, preparing to go all out.
