Oxygen Runs Out, Love Burns Out

I become a firefighter after getting abandoned by my ex-wife, who's a domestic abuser. At first, I think my fiancee, the heroic Captain Cassadee Flack, will be my salvation. But at the blazing scene, the warehouse explodes for the second time due to the scorching temperature. What makes things worse is that the oxygen in my tank will deplete soon. I reach out to Cassadee for help, only to witness her passing the last spare oxygen tank to Colin Halfpenny, the teammate standing next to her. "This is Colin's first time entering a blazing scene. He's terrified, whereas you have enough experience under your belt to deal with this situation. You should hang on for a while longer." I'm choking on so much thick smoke to the point that I almost suffocate from it. Angered, I point at the blinking red light on the control panel. "If I keep suffering from the lack of oxygen, my brain will eventually die! This is the standard procedure of a rescue mission!" Cassadee wears an impatient look. "Why are you being this petty? I promised Colin's dad, who sacrificed himself for me, that I'd take good care of Colin! Can't you be more empathetic? "I thought you could endure pain the best! Back then, you didn't even let out a groan when your ex-wife broke your rib! How is it possible that you can't endure such a small difficulty in this mission? "I finally understand what kind of person you actually are! Someone who's grown up in nothing but pain and misery is bound to be selfish!" I no longer utter a single word to Cassadee. Instead, I use all of my strength to press the emergency SOS button on my helmet. "Command center, please send help immediately. The on-site commander has demonstrated severe misjudgment in handling the situation. I request compulsory intervention."
