On December 19, Yoogeun's mother shared a post on Yoogeun's official Instagram. She stated, 

"I didn't believe my eyes. The breaking news headline. I was so shocked that I read it out loud. Yoogeun, who was more shocked than I was, asked me multiple times. That moment, everything went blank. How am I supposed to explain this to my child? He kept asking repeatedly. Daddy Jonghyun? Why? He's alive, right? Is it true? It's not, is it? 

Daddy Jonghyun went to where your great-grandmother is... Hearing this, Yoogeun cried his eyes out. He then tried to hold back the tears and asked me again. But it could be wrong, right? How did he go where our great-grandmother is? As if he was denying the truth, as if it's too hard to believe. He kept asking.

He kept searching up Daddy Jonghyun's photos on his phone. Then he saw the articles. The child who didn't want to accept the truth kept crying and crying. He's frustrated that he won't be able to see him even if he says he misses him. Mad, sad, and blanked out as if out of his mind. The shock is just too big. He wasn't able to fall asleep. Seeing him trying so hard to hold back the tears, I told Yoogeun to not hold back. Hearing this, Yoogeun sobbed as he called Daddy Jonghyun's name. He then cried himself to sleep.
