The Emperor Wants to Retire

I died and was reincarnated into a hardcore BL novel written by a friend. I was reborn as Ishar, the Emperor of the Luchest Empire, an extra character who works tirelessly every day for ten years, only to be killed by the main character, Belroan, and have the throne taken from him. After four years of nonstop hard work, covering for an older brother who only caused trouble and then died, I finally realized the situation and made a decision. “The only way to achieve my retirement…!” If I can persuade the main character, who hasn’t yet lost his mind, to take over the throne, I’ll be able to escape this work hell and enjoy a peaceful retirement. I brought Belroan, who needed help, to the palace, took him as my disciple, and looked after him carefully. But what’s going on? “I want to stay with you, Master.” I taught him diligently, but somehow… this guy seems a bit… off. – – – “I believe it’s time for you to keep the promise you made when I became your disciple.” The promise to give Belroan the throne. Of course, of course, I should hand over the throne. Now that he’s grown so splendidly, I was ready to give up the throne as soon as we returned. “Didn’t you say that on the day I surpass you, you would accept me as your Empress?” Ishar, who had been nodding along, suddenly froze. In that moment, Belroan gently released the gag and continued speaking. “I’m very happy to become your partner.” His voice, unable to conceal his joy, trembled softly with delight. Ishar spat out what had been blocking his mouth, then looked at Belroan with a tingling expression on his face.
