After a while, Song Xiaodong stood up and suddenly bent down to peck Song Xiaoru on the face.
Song Xiaoru pushed Song Xiaodong away and chided, "Hey, you rascal, what are you doing?"
Song Xiaodong, like a mischievous child, said, "Hehe, I just wanted to kiss you. Every time I kiss you, I feel very happy."
Song Xiaoru gave Song Xiaodong a look and said, "Now that you know I'm not your biological sister, you're still messing around like this? What kind of behavior is that?"
"Sister, being blood-related or not is just something in our hearts. As long as I consider you my real sister in my heart, then you are my real sister. You were in the past, you are now, and you will be forever."
Meeting Song Xiaodong's gaze, Song Xiaoru leaned in and pecked him on the face, saying, "Alright then, we're still real siblings."
"I knew my sister is the best." Song Xiaodong hugged Song Xiaoru.
