After asking Chang Ge, Su Ming'an reconstructed what happened in those eight hours.
...
One hour after sleeping.
"Knock knock." Black Sparrow knocked on the door, holding a small lighthouse figurine in both hands: "This is my gift to you, Su Ming'an."
Chang Ge took it blankly, his eyes somewhat confused... what is the meaning of suddenly giving a gift?
Black Sparrow asked: "Can you tell me how you feel right now?"
Chang Ge: "..."
... He's not Su Ming'an, how should he answer?
Chang Ge answered according to his heart: "I don't know why you are giving me a gift..."
Black Sparrow nodded, turned, and left.
...
Three hours after sleeping.
"Knock knock." Black Sparrow knocked on the door.
Chang Ge stopped playing the piano.
"Your piano playing is really beautiful." Black Sparrow said with a smile, "Can you teach me to play?"
Chang Ge: "Didn't you say the pollution outside is severe? Why are you always walking around at my door..."
