【Dual male leads, interstellar setting, with ABO and some Sentinel-Guide elements, two equally powerful leads, and a rekindled romance.】
Lu Yihan and Shu Chi pilot armored suits through space, battling alien forces.
During the fight, they are betrayed and their location is exposed. The enemy ambushes them, and Shu Chi dies when his armor crashes while covering Lu Yihan's escape.
When he wakes again, he takes the place of Jiang Huai, a street punk who had been beaten into critical condition, and carries on living.
He has lost all his memories of being Shu Chi. The only thought in his mind is that he has to return to the military base.
Dragging his injured body to the base, he collapses and is taken in for treatment.
He wants to stay at the base and become a proper soldier.
Since he used to be a street punk, Lu Yihan, a general, is extremely strict when it comes to selecting recruits and is deeply dissatisfied with him.
Though he stubbornly manages to join the army, Jiang Huai is incredibly hard on him, reprimanding him again and again and putting him through grueling extra training.
He has lost the memories of being Shu Chi, and his abilities are nowhere near what they once were. Yet when driven into a desperate corner, he displays unusual instincts and abilities.
Seeing the street punk before him, who resembles Shu Chi, Lu Yihan is constantly reminded of him. The memories only deepen his pain, and he cannot bear to see this man become a blemish on Shu Chi's legacy...
Under Jiang Huai's strict demands and countless trials, he gradually improves and becomes a competent soldier.
Lu Yihan slowly changes his attitude toward him, and through one battle after another, Jiang Huai gradually regains his memories of being Shu Chi.
You will always be my captain, and I will always be your best partner.
(calculating, biased seme) Lu Yihan × (fiery, stubborn uke) Jiang Huai
Come on, come on, come on⛽
