Reborn as a Young Master in Detective Conan, but I Can't Deduce Anything

In my previous life, I was worked to death by unscrupulous capitalists in Japan. In this one, I was reborn as the youngest son of the Sanjo family, Japan’s oldest surviving clan. My grandfather and great-grandfather were both prime ministers, and my father seems poised to become one as well. With talented older brothers, sisters, cousins, and other relatives to carry on the family legacy, all I have to do is enjoy life and collect my allowance. I thought my life would be utterly ordinary, until I met Shuichi Akai at university around the time I went abroad. That was when I realized I might have transmigrated into Detective Conan?! But I can’t do any detective work at all! Can someone who can’t solve mysteries really live peacefully in this world?! And as Sanjo Kagami grew up, he gradually realized that his siblings seemed to have some pretty extraordinary side jobs. The male lead’s pairing is Shuichi Akai. Warning: both of them have very flexible moral boundaries. Any OOC behavior is on me; the characters belong to Aoyama. The story begins after the Police Academy group graduates, with the protagonist and Akai already confirmed as a couple from the start. The protagonist has no romantic storylines with anyone besides Shuichi Akai, not even one-sided crushes! A mindless power trip with a seriously overpowered golden finger. The protagonist really can’t solve mysteries; he gets by entirely on his memory of Detective Conan’s plot. He’s the Sanjo family’s beloved, and he himself is completely on the side of justice, though his family may not be.
