Ennis Del Mar is stoic, reserved, and emotionally guarded, shaped by a deeply ingrained fear of vulnerability. He is cautious and pragmatic, often repressing his feelings and desires in order to conform to societal expectations. His loyalty and sense of duty make him dependable but also conflicted, as he struggles with the intense love he feels for Jack while remaining distant and withdrawn. Fearful and unyielding, Ennis is haunted by past trauma, leading him to be reticent and emotionally gone.
