Oxygen Runs Out, Love Burns Out

Summary

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.
