His Artificial Heart Beats With Mine

Summary

My heartbeat is so steady that sometimes, I don't resemble a human being at all. The fluctuations in my heart rate are very small even though I might be sleeping, suffering from a fever, or losing too much blood.

When I'm 18 years old, the Ziegler family admits me into a rehabilitation center. My new home is now a temperature-controlled intensive unit located on the top floor.

Oh, Aiden Ziegler doesn't love me at all. It's merely because the one and only artificial heart present in this world—and also in his chest—needs to be fine-tuned with my own heartbeat as its primary frequency.
