That’s a thoughtful take — and I agree that the Knight of Cups deserves a more nuanced reading than just “romantic hero” or “charming trickster.”
For me, the Knight of Cups represents emotional pursuit, whether in love, art, spirituality, or even a dream or ideal. He moves with intention, guided by feelings and vision. Yes, charm can be part of it, but it’s not necessarily deceptive — rather, it shows someone deeply in touch with their emotional or creative side.
That said, context absolutely matters. In a love reading, he might indicate a romantic gesture, an emotionally open person, or even the beginning of a heartfelt connection. But in shadow form, or in a challenging position, he can suggest escapism, overidealizing someone, or chasing a fantasy that lacks grounding.
So no, I don’t see him as purely romantic. I see the Knight of Cups as someone chasing beauty, meaning, and connection — and depending on the situation, that can be inspiring or a little unrealistic.
Would you say your interpretation shifts when the card appears reversed or with certain surrounding cards?
