I Didn’t Mean to Save The Villain

‘Great work, reincarnation. Really.’ Is this a reward for not experiencing even a single bit of love in my past life? I have possessed the body of a frail princess in an unrealistic romance-fantasy Korean novel. Who cares if I have no divine power? I was born with a diamond spoon! Since it has come to this, it’ll be bad if the original plot gets altered.. To maintain this peaceful life, I need to secretly help and foster the male and female lead’s slow-paced romance! Without divine power I had to use others: I turned to the black knights to deal with the villains, help the male lead grow up without worries, stop the villainess’ destruction that will make the female lead cry, and block the villain’s hideous scheme! I have been living harmoniously. “It’s you again, Your Highness.” “Yeah, it is me again. Must’ve been a shame.” My actions have been discovered by the villainous second male lead! But… “…Are you going to meet with the Duke?” “Despite your wariness of me, if you keep frowning your beautiful forehead like that… I will be sad.” “…I thought I would be able to see Your Highness this way.” The villain who is supposedly crazy about the female lead is obsessed with me? Uh, what’s with that look? Why… is your expression like that?
