The Heartbeat Speed Limit Zone

"Gu Huaian, if I hadn't gone to the emergency room that day..."

"I would have found you in a thousand different ways."

"Why?"

"Because once my heart met you, it could never slow down again."

The final warning before your heartbeat loses control is:

"Speed limit ahead. You are seriously speeding. Your fine: love me for the rest of your life."
