I read the novel and the line was, "You are lying to me", it was because Ziyu Ai was saying that he should take his medicine and go to sleep so he could feel better, but Zishu replied with "You are lying to me" because after the harshest of nights he endured for years, even if he does get a goodnight sleep, he still feels the same, the half of his bed ice-cold and empty ty, leaving deeper scars in his heart.
What did Zhishu mean - Chapter 52 pg. 15 when he said
“You lied to me.” to Dr. Ai? I don’t understand.
Can someone explain.
