After Being Reborn as My Own Widow, I Was Inherited by a Disabled Prince (ABO)

(It's all the fault of my draft folder. Let me fill in the holes slowly. Groveling.) A story about a straight alpha major general reborn as an omega, then mysteriously "inherited" by an imperial prince. Blurb Major General Dorian is hailed as the Empire's most saintly soul. Perfect in every way, he tops the list of "Alphas the Empire's Citizens Most Want to Marry" year after year. He has a unique, ice-cold vodka pheromone, yet an "accident" leaves him lost in the vast reaches of space. Some suspect a Zerg ambush, while others believe the military is behind it. As the whole country grieves, Dorian is reborn in the badly injured body of a stranger, an omega. For no reason, his body gives off the scent of vodka pheromones, making him seem as if he had been marked by himself. A voice comes from above: "Report, sir! We found the general's pheromones in the ruins! But... it's an omega..." Before Dorian can recover, his former subordinates surround him protectively. His adjutant says in anguish, "Madam... please accept my condolences." Dorian: "..." Well, look at that. He's become his own widow. Dorian thinks it over. So what if he's a widow? His old body must have been smashed to pieces, and he's also lost the important memories from before his death. This identity might be convenient for finding out the truth about how he died. And so, "General Dorian Dies a Glorious Death" and "Alleged General's Widow Tries to Grab His Estate" become hot topics. Before Dorian can succeed at his household intrigue, the Sixth Prince of the Empire, Onisa, returns from battle. He and Dorian once fought side by side before going their separate ways, and were "good brothers." Another top alpha, Onisa has not only recovered from paralysis below the waist and won a great victory, he has also ambushed Dorian on the way and guarded his estate so fiercely that no one is allowed to touch it. Dorian thinks, Thanks, brother. He plans to fake his death and leave the capital, where undercurrents run deep, before deciding what to do next. But the Sixth Prince suddenly loses his mind and announces that he and General Dorian were as close as brothers, so he will inherit the general's entire estate, including his widow. Dorian: "...?!" Dorian is dumbfounded. After he's been washed, dressed, and stuffed into the Sixth Prince's bedroom, the lunatic holds a glass of vodka and says, in a gloomy, sorrowful voice, "I would never touch you. I only want to smell the familiar scent he had. No one else in the whole Empire has pheromones as pure as his." Wrapped in a blanket, Dorian thinks for a long while before suddenly understanding. The Sixth Prince is a pervert who likes the pheromones of alphas! Onisa: Oh, my love! Before I could even speak, it was already over! Dorian: Oh, brother... You should get treated for that illness! Straight alpha turned omega, superb actor but emotionally slow, general bottom X lovesick secret admirer, tsundere turned yandere, disabled prince alpha top. (The top uses a wheelchair and plays the fool early on, then later races around in a mecha with his wheelchair.) One-on-one romance, happy ending. (The pheromones here follow custom rules: After an omega is marked, their pheromone scent is covered by the alpha's. Only their partner can smell the omega's own pheromones.) Theme: Say your love out loud!
