姫君の影武者を務めていますが、シスコン兄殿下が「その程度で我が妹になりきったつもりか？」と執拗にダメ出ししてきて正直ウザいです

I pride myself on being a first-rate body double. Not only do I look like her, I can imitate her every move.

But that spiteful Prince Sylvan, the princess’s older brother, always sees through my disguise on the first try and says “Do you think you’ve become my beloved sister?”

Yes, the prince is a serious siscon.

“Sigh, you are as naive as ever. Do you mean to impersonate my sister?”
