Song Yu called out gently, "Second Brother?"

"I've told you before, you can't call her sister."

Song Yu's expression froze, and her face gradually turned pale. "I…"

Lu Nian looked away from Song Yu's face indifferently and walked out.

Song Yu looked at Lu Nian's back as he left with an aggrieved expression. She bit the corner of her lips lightly, and her heart felt like it was being clenched tightly by a hand. The pain was unbearable, and even breathing became difficult.

Ever since Song Yu could remember, Second Brother seemed to especially dislike her. He was clearly a cheerful person, but every time he saw her, his expression would be very dark.

In the past, she did not dare to be especially close to Second Brother. Every time, she could only look at him from afar.
