Catlin is going through security, looking at the long line ahead, holding a plane ticket to the UK.
Han Kai’s parents are in the UK, and actually, he had wanted to visit him before.
Han Kai has not returned, nor has he contacted himself, he doesn’t know how to find him, he doesn’t see him at his home, nor at his workplace, only then did she think of his parents living in the UK.
He might be in the UK!
She thought to herself like this.
Looking at the long line ahead, she doesn’t know what kind of mood she is in. It seems she wants the line to move...
