The High-Spec Scion’s Body Double is More Popular Than the Real Thing

​Since I’m a body double, rom-coms are off-limits—so why are these young heiresses throwing themselves at “me”?! ​Kei, an utterly ordinary high school boy with zero presence, is given a top-secret assignment one day: serve as the “body double” for Eitarou Hoshimiya, the heir to a massive corporate conglomerate, and attend an elite private high school in his place. ​Despite being notorious as a total scum-of-the-earth playboy, Eitarou is insanely popular due to his high-spec background—a real problem child. To avoid blowing his cover as Eitarou’s body double, Kei must play the dual roles of a tr*shy scum-bag and a irresistible heartthrob. ​However, Kei’s genuine sincerity cannot be completely hidden, and before he even realizes it, the academy’s high-class heiresses fall deeply in love with him one after another…?! ​The more he acts like a tr*shy scion, the higher his favorability magically skyrockets! Even while playing the part of a popular heartthrob, as a body double, romance is strictly off-limits! ​Here begins the harem rom-com triggered by a fake scion life!
