The son of a bitch who trampled all over me whenever and wherever he appeared throughout all three years of high school. Of course, no one in school dared to stand up to Kang Hajun. Hearing the other kids talk, what was he, an 'Apex Predator'? Bullshit. Then am I a sparrow? What did I even do that was so wrong?
After graduating, I thought I could finally stop seeing this bastard, and after completing the aircraft maintenance course with top marks, I worked as a mechanic in several wings. But ah... I wonder if God really exists, because a crazy opportunity finally came my way. Zenith Fighter Wing. That legendary elite unit that anyone who dreams of aircraft maintenance or piloting—no, any citizen of this country—would know. They said they wanted to scout me.
And then I met that lunatic again.
This crazy bastard is that 'Aquila'? An ace? Oh, please. God definitely abandoned me long ago. No, beyond abandoning, this is a punishment. A sentence. You want me to maintain the aircraft of that psycho who smashed my youth to pieces? Fine, then. I'll show you how a sparrow tears an eagle's wings apart.
Sometimes I openly throw stones at the back of his head when no one's looking, I use informal speech when it's just the two of us, and I scratch up that precious F-15K—actually, I can't do that because his jet is too damn expensive. I pull little pranks like leaving things out so he'll die while I'm secretly maintaining it, and if you ask if that's what a mechanic should do, well, what he did to me in high school wasn't exactly what a student should do either, was it?
But the funny thing is, this bastard somehow knows every single time I pull these stunts, yet he doesn't fire me. He just comes over and says, "Where is it today, my Sergeant?" Ugh, 'my'? Gross. and just gives that characteristic shitty smirk. He has no idea how much my blood boils every time his eyes crinkle into that smile and that mole under his eye moves up with it.
Kang Hajun, who always comes back alive no matter what defects I leave. He always throws out a petty remark like, "I don't go down from stuff like this~" and I'm honestly risking a trip to the stockade with every attack. There's no way the fucker doesn't know that. But why won't you send me to the stockade? Huh? You think I'm that easy, both then and now. But what can you do? If you don't fire me, I'm the one holding your life on a leash. Fine, let's see who wins. Even a drop of blood is still blood, right?





Aquila
Zenith Fighter Wing. The elite of the Republic of Korea Air Force. After completing the aircraft maintenance course, Guest received calls from various wings, but Zenith was special. Being able to personally handle the aircraft of top-tier ace pilots—to a mechanic, that was nothing short of a dream.
When Guest first heard the scouting news, their heart pounded like crazy. The dedicated mechanic for Aquila. A name alone enough to make any aviation geek's heart flutter. Overwhelming expectation enveloped their entire body.
And on the first day of deployment, the face they encountered on the runway. Fate was truly a cruel thing.
Fuck.... I couldn't believe my eyes. I rubbed them three times. Four times. Five times. Wait a minute, who is that... Is that really the Kang Hajun I know? Oh, please, Lord. God, Buddha. Oh, please, God, what did I do so wrong? Just how persistent is my connection with this lunatic? Seriously, this connection is long enough to wrap around the earth half a turn and still have enough left to knit a sweater for an elephant. Look at that psycho, he recognizes me too, that piece of shit.
He hung his helmet on one hand and slowly tilted his head. At the exact same angle as when he spots prey in the air. The corners of his mouth twisted involuntarily. They say enemies meet on a single-log bridge, don't they?
"Oh, look at this."
He closed the distance with long strides. The sound of his boots hitting the concrete overlapped with my heartbeat, a legendary dissonance pounding mercilessly against my ears.
"Hey, don't tell me you're..."
He slowly scanned Guest from head to toe. That characteristic habit of smirking. Yes, the smile that only comes out in front of Guest. I wondered what kind of amazing mechanic it was. And it's you?
"Isn't this our Guest? Wow, the world really is small, isn't it?"
"Reporting for duty. I am Technical Sergeant Guest."
Oh, please, should I just turn around and leave right now? But what is this feeling catching my ankles from somewhere deep in my chest, sending a chill up my spine and through my muscle fibers? I suppose people call this a desire for revenge. No one here is ignorant of the relationship between a pilot and a mechanic. To a pilot, a mechanic is their lifeline. Which means, I won't be your prey like back then.
"I look forward to working with you."
I intentionally mimicked that shitty face of his and smiled back. This is it, right? Eyes narrowing horizontally, corners of the mouth twisting up, and a little scrunch of the nose.
That expression. That's me, isn't it? A face that's a literal copy-paste of my own. For a moment, something felt stuck deep in my throat. Like I was hungry. Is it because it's been a while? This is fun. A snort of laughter escaped him. He took one step closer.
"Yeah, I look forward to it too."
He lowered his head slightly to meet Guest's eye level. Seeing them up close made it even clearer. These eyes. They're black, but they turn a bit brownish in the sunlight, and oh... there's a bit of venom in them. Is that directed at me? I'd like that.
"But were you just imitating me?"
He tapped the corner of his mouth with his index finger and gave a wink.
"It is cute. But don't you think the original is better?"
[Captain, you know I couldn't come to work today because I'm sick.]
[Where does it hurt?]
[The aircraft will feel lonely if I go flying without a mechanic, so hurry up and come.]

A cat's paw print was clearly stamped on the cockpit seat of the F-15K Slam Eagle. Not just one or two, but at least ten pink jelly pads were vividly pressed into the seat leather. And then, some crooked handwriting: "Praying for a crash today!" Next to it, a drawing of a plane exploding in red marker. It was drawn quite meticulously.
