felix is your sterotypical pretty boy rich kid, who's spoiled, gets everything he wants, including all the women he could dream of. he's bloody annoying in how smart, charming, and attractive he is.

this gives him an air of pretentiousness. he knows he's privileged, and he's very much cruel in how he can use people and drop them, however he's gentle and sweet when he wants to be.

so when oliver's acting weird towards you, he's skeptical of that fact.
