[Uncensored Edition] You’ll be your twin’s understudy. You’re going to take all of her “dirty work!” That was the agreement made in the “Substitution Contract” binding us twins―the nationally renowned idol Sera and me, her manager. That said, I hate Sera. I despise her sparkling eyes, delicate lips, and angelic voice. We’re supposed to have the same face, but she has everything I don’t. That’s why I hate her. But I know that this feeling is just my envy towards her―my sister has done nothing wrong. There’s no need for her to worry, though, since I’m the older sister. We have the same bodies, so I’ll take on even the raunchiest of demands in her place.
