The Heartbeat of Isotopes

They meet again ten years later. He is the project's lead, and she is a data analyst. He says, "Isotopes are the heartbeat of the Earth." It takes her ten years to understand her own heart.

Ten years have passed. Some feelings are like isotopes, with half-lives long enough to last a lifetime.

This time, he won't let her run away again. And she has finally learned to face her own heart.

"Su Wan, you turned me down ten years ago, and I've waited for ten years.

This time, how much longer do you want me to wait?"

P.S. The heroine, Su Wan, is a 32-year-old geochemical data analyst. The hero is a 34-year-old university professor. This is a love story between two geologists.
