Transmigrated as the Villainess Fake Young Lady, Please Spare Me, Female Lead Sister

Transmigrated into the game as the villainess fake daughter Claire of the Grendel family, but super timid. It's not my fault, who made the original female lead not only the real daughter but also a overpowered protagonist with cheat abilities, I can’t mess with her! System: "Go, slap the real female lead twice!" Claire: "Sister's skin is so nice let me touch!" System: "Go, splash milk on her face!" Claire: "Sister you don't know this is called a face mask it's good for the skin!" System: "Go, tie her up and humiliate her properly!" Claire was holding the rope hesitating still not sure what excuse to use this time, when she saw real female lead Raphtia herself bringing her wrists forward, cold eyes overflowing with amused teasing: "Looks like Claire wants to play bondage today, come then... why are you backing away again? If you keep being this timid, I might reverse our positions." "Uwah? Sister, I was wrong, don't tie me up——!" System: At this point, maybe I should just upgrade to a yuri sweet romance system...
