Abandoned Boyfriend of the Apocalypse

During a zombie-extermination mission, I end up getting infected with the zombie virus for the sake of protecting my squad. But Emilia Campbell, the team captain as well as my girlfriend, decides to give the only antidote to another team member, who has secretly run away from the squad, only to get infected. Her excuse is that she should avoid being partial. With red-rimmed eyes, she promises me, "Trust me, Zack. I'll definitely find another antidote for you during the three-day incubation period of the virus." I can only nod in response while enduring the scorching pain flaring from my body. On the second day, Emilia actually returns with an antidote. But the second she's about to inject it into my bloodstream, Dustin Nott, a member who has never left the campsite, suddenly frowns. "My head hurts so much, Em… What if I'm already infected with the virus?" Emilia doesn't hesitate to pass the antidote to Dustin in front of everyone else. "Dustin is a part of the team as well. It's my fault as the captain for not taking care of the squad if anything happens to him. "Zack, you're the vice leader as well as my boyfriend. I must be impartial." That's when I notice the smugness crossing Dustin's eyes as well as Emilia's righteous expression. Fury bubbles within me at that moment. She must be impartial, huh? Fine. Emilia will soon understand that the squad would never have survived to this point without me. After all, I'm a perfect evolved specimen—a human being that only has a 0.1% chance of overcoming the zombie virus and evolving into a powerhouse in this apocalypse.
