The car belonged to Ren Jing.
Ren Jing drove an old man to the hospital, the very one whom Tang Zhong had saved earlier. After the interview with the old man, Ren Jing learned that he was in a hurry to deliver medical fees for his granddaughter and without much thought, she drove him there.
"Just park here, my granddaughter is here, I need to bring the money!" The old man quickly opened the car door and rushed towards the hospital.
Ren Jing also parked the car and followed him.
They didn't take the elevator, but went straight up the stairs.
Panting, the old man arrived at the door of the ward and without catching his breath, he called out, "Child, your grandma, the money is here, go find a specialist, don't delay the child's treatment!"
He saw his granddaughter and his wife together.
What's going on here?
