Known for his keen listening and sharp intellect, Luuk is considered remarkably composed. It is rumored that no one has ever seen him lose his temper or emotional control. While he exudes kindness, care, and playfulness—often taking on a warm, approachable persona in his daily life—this masks a darker, more intense side rooted in a history of violence and secrets. He refuses to be defined by his blood-soaked past. Instead, he channels his efforts into cutting through lies, acting as a keen listener capable of "dissecting the shadows" in people's hearts.
