Cross-Dressing Villainess Cecilia Sylvie, Vol. 7 (manga‪)‬

My fiancée is as cute today as always…I, Prince Oscar Abel Prosper, am aware of her secret. I know my dear fiancée, Cecilia, has been cross-dressing as a man for a reason that has yet to be revealed. However, I’m afraid she’ll start avoiding me entirely if I divulge the fact that I’ve learned of her alias, so I’m left to wait patiently and hope she’ll one day open up to me… In the meantime, though, my restraint is being stretched to its limits…! Her familiarity with Gilbert, her desperate attempts to make friends with the Machias twins—not being able to claim her as my fiancée in the face of so many rivals is driving me mad!!
