Otome Game no Akuyaku Reijou nanoni Ouji to Ero Tenkai ni narundesuga!?

Rene is reincarnated into an otome game "Magic Melt" as the prince’s fiancée villainous character, who is facing a tragic ending. To avoid the bad ending, she decides she has to help get the prince and the heroine of the game together. However, due to her extreme clumsyness, she botched the first encounter between heroine and prince and had to be taken to the infirmary instead of the heroine. “I know you don’t actually love me since every time you say you love me, i cant see your feeling in your eyes .” Oh no, has the prince found her out? And my disinterest in him makes him want me so badly he can’t bear it?! "Don’t think you can escape me that easily." I thought this was the world of a normal otome game and not an R18 game?
