You Can Have My Back, Vol. 5 (light novel) - Beyond the End of This Love I

Josef has come to the royal capital to serve his lifelong master. Lucas, the lieutenant general, gives his unchanging love to his late beloved. Dirk, adjutant to the general, who has made an unusual name for himself as a commoner, despite his facetious personality. The twists and turns of fate bring them together to face an incident that rocks the foundation of the kingdom, and Josef falls in love with Lucas in the battlefield. But Josef is suggested he become Lucas’s adopted son so that he may continue to live in the royal palace, where birthright purists run rampant. As Josef faces his own conflict, unable to let go of his yearning, Lucas, the object of his affection, points out how naïve he is, and Josef reels. On impulse, he heads out into the seedier parts of the city at night, but who appears before him but Dirk, more furious than Josef has ever seen him before...
