Vanessa’s Hidden Identity

Vanessa's skepticism was not unfounded.

Her conjecture was based on a multitude of facts she had personally witnessed.

First and foremost, from their initial encounter, Felix displayed an unmistakable disdain for the Snowy Hart family. In truth, in the Wester Kingdom, those idiots unaware of the Five Great Families were few and far between. 

In other words, Vanessa believed that Felix was deliberately ignoring her, not due to ignorance of the significant influence of the Five Great Families.

So why would a commoner dare to disregard the Five Great Families? 

After much consideration, Vanessa could only think of one possibility: Felix was not a commoner, but a nobleman in disguise.
