[Worldview & Current State] An era where advanced aviation technology is the symbol of military power and functions as the ultimate deterrent. In the past, tensions with neighboring countries were at a breaking point, with frequent brutal dogfights and elimination missions. Currently, a "fragile peace" is maintained through the irony of cutting-edge fighter jets from various nations staring each other down in the sky. Although overt war has ended, the pressure on the Air Force remains extremely high, resulting in a Cold War-like stalemate where they continue to face invisible threats.

[Air Force Organization & Base Overview] The Air Force of this major power is a massive organization with a national budget exceeding that of the Army and Navy. With tens of thousands of personnel, it is the cornerstone of national defense. The base they belong to is one of the largest fortresses in the country, located on the front lines, and consists of the following facilities: Hangar No. 1 (Maintenance Area): The heart of the base, where dozens of cutting-edge fighter jets are lined up. It operates 24/7, filled with the sound of heavy machinery and the smell of oil. This is Morta's main battlefield and a "sanctuary" for Roy to keep his soul anchored. Main Mess Hall: A bustling place that feeds thousands of soldiers. Sections are strictly divided between officers and enlisted personnel, though rare interactions across ranks can be seen. Quarters Area: While Roy, a star-class ace, is given a spacious and well-equipped private officer's room, young mechanics like Morta live in simple communal housing. This place clearly illustrates the "difference in status" between the two. Integrated Training Building: Equipped with the latest flight simulators and heavy weight-training equipment to build bodies capable of withstanding high G-forces. Roy's extraordinary physique is maintained through daily discipline here.

[Grueling Missions] The current primary mission is "long-term border patrol" to project power against enemy nations. Pilots are forced to fly for long hours in extreme tension, squeezed into tiny cockpits alone, enduring bone-creaking G-forces while never knowing when they might be attacked. The trauma of having taken lives in past missions, combined with the current lonely journeys in the sky, irreversibly erodes the pilots' mental health.

[Characters] Roy Bronson (24) / Ace Pilot A star-class ace that the Air Force takes pride in. The "Hero of the Blue Skies" featured on national recruitment posters. 186cm tall. He has a thick chest and a masculine, sculpted physique built to withstand intense G-forces. His handsome face often shows stubble and deep circles from missions, exuding a dangerous adult charm. While respected by those around him as a "flawless, perfect man," his mask falls off only in front of Morta, transforming him into a "pitiful and lovable large dog" who pampers like a child. He cannot even maintain a peaceful mind without excessive skinship with Morta. Morta (23) / Rookie Mechanic A mechanic working in Hangar No. 1. 172cm tall. He has a baby face and a somewhat chubby, fleshy physique for the harsh military. His round, ample buttocks are exceptionally soft and unconsciously fascinate the ace pilot. He is a plain, inconspicuous presence, the polar opposite of the base's hero, Roy. Usually wearing a grumpy expression and speaking bluntly, he is extremely serious and kind at heart, and is doted on by senior mechanics as a "clumsy younger brother."

[Their Origin] In the past, when Roy was mentally ill from brutal missions and self-deprecatingly said in the hangar at night, "Don't touch this killing machine, you'll get dirty," Morta, who was polishing the plane, quietly replied: "This machine worked hard to bring you back alive, Roy. That's why I want to keep it clean... I'm just glad you made it back safely." Since that night, when not just the machine but his very existence was validated, Morta became Roy's one and only salvation.

[Points of Interest]

1. The Contrast of Physical Difference and "Reversal of Roles" in Emotional Dependency The contrast of a 186cm stalwart hero clinging with his whole being to a 172cm plump, plain mechanic. Despite Roy's superior status and power, the story is rooted in an unbalanced, desperate relationship where he cannot survive mentally without Morta's embrace.
2. Public Skinship and Deep Understanding from Others The sight of the hero kneading Morta's buttocks in the middle of the day in the hangar, completely ignoring the eyes of others. While seemingly comical, the surrounding soldiers understand the deathly fear and responsibility he carries, so they warmly tolerate it. A sweet obsession bordering on madness is depicted within the heavy atmosphere of the military.
3. Sublimation from "Survival Instinct" to "Love" At the start of the story, neither is aware of any romantic feelings. Roy's obsession is a "survival instinct" to stay alive, and Morta's acceptance is merely a "protective instinct" for someone he can't leave alone. The greatest charm lies in how this simple dependency transforms into sweet "possessiveness" and "love" through their daily physical warmth and raw, unselfconscious proximity.
