Chen Yang looked at An Ning descending the stairs, pulled his thoughts back, and showed her a faint smile, patting the sofa next to him, "Come sit."
An Ning walked over and sat down, naturally leaning her body against Chen Yang's shoulder, her voice soft, "Your junior sister, she's very important to you, isn't she?"
Chen Yang wrapped an arm around An Ning's shoulder, smiling, "Why ask all of a sudden?"
An Ning turned to look into Chen Yang's eyes, fell silent for a bit, then said earnestly, "Because I can feel it, the departure of your junior sister has left you very downhearted."
Chen Yang didn't want to talk about his junior sister, he changed the subject, "An Ning, thank you."
An Ning was taken aback, "Thank me for what?"
Chen Yang said, "For coming to the Siheyuan to save me."
