Goodbye

"Does your Master have heart palpitations?" The doctor asked. 

"Heart palpitations?" The guard was stunned when he heard this and shook his head: "No! My Master has never had heart palpitations, and this has never happened in the past before either."

The doctor glanced at him and said: "However, based on what you told me earlier, your Master suffered heart palpitations from his huge change in mood. If this hasn't happened before, maybe it's because he's never had an attack, and this time it's happened due to the impact of stimulation."

"But, my Master didn't…" The guard wanted to say something, but he was interrupted by the doctor.
