"Xie Cheng, are you childish? Are you a child?" Yue Xi was used to Xie Cheng's unreasonable troubles and said casually. Unexpectedly, Xie Cheng took a grudge and imitated her tone every day to tease herself.
"I hope you will always be a happy little sister."
"Big brother, you too!"
"It's enough for me to have you." Xie Cheng said and hugged Yue Xi's shoulders. A girl and a boy echoed each other in the sunset.
Concept: The girl follows the boy's shadow, and perhaps becomes the boy's shadow, indistinguishable.
