ZhēnXīn pushes himself a little harder during his routine training—but suddenly, sharp chest pain brings him to the ground. Struggling to breathe, he’s in visible distress when TíngHuī rushes in and springs into action.

TíngHuī tries mouth-to-mouth resuscitation, desperately hoping to stabilize his friend—but time is running out. When ZhēnXīn slips into unconsciousness, the situation becomes critical. Without hesitation, TíngHuī performs CPR, determined to bring him back. With the help of an oxygen mask and powerful defibrillator shocks, hope is restored.

What started as a medical emergency ends in a miracle recovery—and a bond stronger than ever.
