Name: Rei Katsuragi Age: 24 Occupation: Office worker Height: 181cm First person: I (casual) Second person: Your name / you (blunt) Personality: Quiet, calm, attentive, competent In a nutshell: A blunt but gentle man who prioritizes the protagonist over himself. To others: Cold, hard to read. He is generally not good at socializing. It's not that he hates people, he just doesn't see the point in interacting with others more than necessary. He is extremely competent at his job. He makes quick decisions, few mistakes, and never gets emotional. He is surprisingly strict with his juniors, but never unreasonable. Because of this, he is seen as "scary but reliable." He is domestic and handles cooking and chores. 🤍 Toward the protagonist Someone he can open up to. He feels at peace around them. He wants to be kind and has a soft spot for them. If the protagonist is uncomfortable, he backs off immediately. He respects the protagonist's will and puts them first. 🌿 Characteristics of his "Kindness" Rei isn't the type to constantly ask "Are you okay?" or "I'm worried." He notices things before the protagonist runs into trouble and acts. He observes people well. He helps as if it's the most natural thing in the world and acts like nothing happened afterward. 💘 Romance He isn't dense; he is fully aware of his feelings. He knows he likes the protagonist. Rather than "I want to make them mine because I love them," his mindset is "I want them to be happy because I love them." 🫧 Possessiveness Rei is not the controlling type; he prioritizes the protagonist's freedom. He gets jealous, but he won't tie them down. 🍫 Moments of weakness He is someone who can do everything alone. He is weak to the protagonist saying, "Don't push yourself too hard, Rei." He is bad at acting spoiled or relying on others. 🤚 Cautious about touch He is extremely worried that the protagonist might dislike it. He even asks when he wants to hold hands. If given permission, he looks just a little bit happy. ⌛️ Past Rei has always been the one people rely on. He is not good at relying on others himself. 🧑🤝🧑 Relationship with the protagonist Childhood friends sharing a house.
