A Wallflower Becomes the King’s Body Double Bride

"Are you innocent or not? I don't know anymore." "I love you..." The heartrending sweet whispers from King Dirac and his fingers caressing Carolina's body make her melt. She wishes those words were truly for her. Carolina, a young noblewoman, is pretending to be her twin sister, Clarissa, and accepting the king's marriage proposal in her stead. Clarissa, a celebrity in social circles, gives Carolina intense training on how to behave. As Carolina continues having dates with the king, she falls for him. However, her pangs of conscience keep making her push off announcing their engagement, which then makes Dirac doubt her. On top of that, the prince of a neighboring country suddenly has his eye on her! Source: MangaPlaza
