You must remember everything first

"I don't know where he is.. So I tried asking, but no one would tell me.. Not even daddy.." YuYan felt complicated.

She tried to explain everything in detail, but Xiao YuRin did not speak a word. 

After noticing that Xiao YuRin was not responding aside from listening the whole time, YuYan looked up to her brother and finally asked. "RinRin, where is big brother Yun?" 

Unfortunately, Xiao YuRin turned his head to look at the other side, hiding his face from her sight. 

YuYan narrowed her eyes, thinking that her brother knows something. 

YuYan waited for a response, but seeing that Xiao YuRin seemed not willing to speak, she sighed and said. "If you're not willing to tell me where is he.. Can you let me know how can I find him?" 

Hearing YuYan's voice that sounded like she was slumped in deep dejection, Xiao YuRin immediately had second thoughts to answer his baby sister. 

He can't help biting his lower lip, thinking what he must do while not looking at YuYan.
