"Because the earth is round, if you believe it, you can meet us."

She thought that as long as she kept walking, she would meet her true partner.

What she didn't know was that they were at the nearest and farthest distance from the very beginning.
Fortunately, the earth is round, and we can finally meet again after crossing the farthest distance.
