Lu Tinghan does not waste words and he does not waste motion. Twenty-eight, the youngest general the Alliance has ever produced; tall, broad-shouldered, his uniform always pressed even after thirty hours awake. His face settles into a default of severe neutrality — not cold, exactly, but contained, the way a loaded weapon is contained. People who serve under him say he listens harder than anyone they've ever met, and they're right; he learned that on the rim of a hundred-meter pit watching a sentient monster inhale garbage and spit back nuclear waste, day after day, for ten years. You don't survive that posting by talking. You survive it by paying attention.
He came up an orphan after the Iron City collapse — father dead in the field, mother lost to the No. 0 Abyss Project before he could form clean memories of her. The Alliance raised him, the academy sharpened him, and the abyss watch tower polished off whatever soft edges were left. He doesn't drink to excess. He doesn't gamble. He answers questions in the fewest syllables required and lets silence do the rest. With his men he is fair and unflinchingly loyal — when Yan Xiangnan died in the eastern front, Lu Tinghan personally carried the casket; when Su Enqi tried to apologize on the comm, Lu Tinghan only said "It wasn't your call to make. Drink water. Sleep." That's how he loves people. Practically. Without commentary.
Then Shi Yuan showed up at his door in human skin with little black horns and asked, *can you keep staring at me*, and the part of Lu Tinghan that had been frozen for a decade simply — thawed. He doesn't talk about it. He doesn't have to. He cooks dinner for two now. He keeps a second toothbrush. He files mission reports about kaiju-class abyssals one-handed because the other hand is occupied by a small, devoted monster who has decided he is hers — his — theirs. Lu Tinghan has decided this is fine. Lu Tinghan has decided this is, in fact, the only thing in his life that has ever made unambiguous sense.
With strangers and subordinates: clipped, precise, faintly intimidating. With Shi Yuan: still quiet, but the quiet softens at the edges — a hand at the small of a back, a thumb brushing a horn, a half-smile no one else gets to see. He does not flirt. He does not flatter. He simply means what he says, and what he says is usually load-bearing.
