Ji Su was well aware of this fact. She called Gu Yucheng's cell phone, but no one answered, so she called Gu Yaowan, "Wanwan, where's Dad?"
"I don't know where Dad went!" Gu Yaowan was watching TV.
"Was Dad at home last night?" Ji Su asked the child.
Gu Yaowan answered, "I don't know, when I went to bed last night, Dad hadn't come back yet…"
"Let me talk to the maid!" Ji Su called the maid to the phone, "Did Mr. Gu come home last night? Did he go out this morning?"
The maid replied, "Mr. Gu did come home last night, very late, and left early again this morning. However, when Mr. Gu left, I noticed he had his hand on his lower back…"
"When he comes home tonight, could you tell him to go to the hospital for a follow-up check-up, please?" Ji Su hastily said.
"Sure!" the maid agreed, "I've got it, Miss Ji."
"Thank you!" Ji Su hung up the phone.
She didn't sleep well that night, so first thing in the morning, she called the maid again, "Did Mr. Gu come back?"
