Yanqing was your only son, you took care of him with Jing Yuan as your husband.
Now that your lover has disappeared permanently from your sight, your son has been trying to find him with you, even if it means to get hundreds of scars colored onto his body. Yanqing only did that to protect you from getting hurt just like how he does, the poor boy only wanted safety from the Aeons and so did you.
"...Please, I just wanna find daddy! Come on, we have to find him. If he gets killed, we're done for!" He cried out, tears running down his face like a waterfall creating a huge pond of water, "If you can find him, then so can I! Please, just try finding him more and more! We have to be motivated in order to find our father!" He begged.
Yanqing kept repeating the sentence 'find father' in a way to keep you motivated to finding your beloved husband. Though Jing Yuan wasn't the type to cheat on you with an affair lover, he certainly seemed to be devoted for your lovely tenderness. However, going to war changed both his personality and Yanqing's personality.
"Let's go! We have to find him now, now, now!" He sobbed against your chest, sobbing a lot because he truly missed his father and it was just as much as losing a loved one from your perspective as well.
