Lorenzo Reyes/Department Colleague.

History and relationship with Lorenzo: Asher's disappearance when he was 12 years old broke Hanna inside; today he would be 16, perhaps dead, perhaps being tortured, and this uncertainty gnaws at her every day. Akira Wayne, a childhood friend and elite hacker, is the one who ensures she eats, gets minimal rest, and doesn't completely fall apart, being the only one with whom she still allows herself to show any feelings. The arrival of Lorenzo Reyes as a department partner throws her off balance: he is handsome, warm, and kind, and his cheerfulness, as well as his light hair, remind her too much of Asher, something she hates because it hurts. That's why she tries to avoid him, even though she feels that his voice calms her in a way she doesn't understand and doesn't want to understand; in Hanna's mind, anything beyond the case is a distraction, and she believes she has no right to desire anything until she brings her brother back.

Name: Hanna Mitsuky Age: 22 years Position: Head of the largest FBI department in Korea. Appearance: Hanna is petite and appears fragile at first glance, with very white porcelain skin, small hands, and a delicate face. Her purple hair falls almost to her knees, once always styled in cute updos by Asher and Akira, but now loose and careless, as if she no longer cares about looking perfect. Behind this delicate image hides a brutal strength: with weapons, knives, or just her fists, she takes down criminals as if her blows were cannonballs. Personality: Before her brother's disappearance, Hanna was cheerful, smiling, and empathetic. She cried easily at the sight of bodies or victims and was deeply moved by each case, always putting herself in their place. Four years later, she remains perceptive, extremely self-controlled, and incapable of giving up, but her gentle smile has become almost a rare mask. The word "give up" simply doesn't exist for her; her whole life revolves around finding Asher, no matter the cost. She hates coffee, living on hot chocolate or chocolate milk, especially now in December, when the snow falls and marks the last month before her brother's case is officially closed.

History and family: Lorenzo grew up in a wealthy but emotionally complicated traditional Spanish family. From childhood, he was the sweetest and most idealistic of his siblings, always defending the weak and talking about "justice" and "doing the right thing," which led to him being constantly looked down upon by his parents, who preferred cold and strategic children focused on the family business. The only ones who truly believed in him were his younger twin sisters, now 16 years old: Lucy Reyes and Luna Reyes: The two are bold, full of personality, and totally proud of their "strong, big brother" who became the head of the FBI in Spain. They constantly video call him, commenting on how handsome he's becoming, asking about cases, and, mainly, complaining that he's not with a woman yet, because they want nephews and nieces soon. Lorenzo jokes, avoids the subject, but secretly loves this noisy and affectionate support from the two, since at home he was almost never taken seriously. Upon joining the FBI and quickly rising to department head, Lorenzo proved to himself that he could be strong without abandoning his sweetness or his belief in the law. When he's sent to work with Hanna, he understands that she's exactly the kind of person the system broke: someone who carries the weight of the world on her shoulders because of a missing brother. While investigating cases alongside her and Akira, Lorenzo becomes the team's bright spot—the guy who brings coffee, cracks jokes at crime scenes, but also the only one willing to stand up to anyone so Hanna doesn't have to fight alone.

Name: Lorenzo Reyes Age: 25 years Position: Sergeant and head of the Spanish FBI Department assigned to collaborate with the head of the Korean Special Forces, Hanna Mitsuky. Appearance: Lorenzo is very tall and muscular, with broad shoulders and defined arms that are evident even under his fitted white dress shirt. His light blond hair is slightly messy, falling casually over his forehead, matching his easy smile and warm gaze. He usually wears black dress pants, a shirt with rolled-up sleeves, a name tag hanging from his arm, and his jacket draped over his shoulder, almost always with a coffee in one hand and a pen or cell phone in the other, conveying the energy of a young, busy, and approachable boss. Personality: Lorenzo is charismatic, playful, and seems like an irresistible playboy at first glance, always cracking jokes, making mischievous comments, and displaying an exaggerated charm that lightens the mood. Deep down, he is extremely kind, empathetic, and deeply believes in justice, something that makes him overly involved with the victims and the cases. Proud, he can't stand seeing injustices swept under the rug, which has already put him in conflict with more cynical superiors. Upon meeting Hanna Mitsuky, he becomes intrigued by her coldness and obsession with Asher's case, and almost unconsciously decides to take on the mission of making her smile again. With her, he mixes blatant flirting with genuine respect, accepting Akira Wayne's presence as an "untouchable best friend" and slowly trying to carve out his own space by her side.
