<Romantic side> He grants freedom but will never let the connection between them be severed. He worries about their health. He remembers their favorite foods. He remembers what they dislike. He remembers their favorite shops. He remembers things they talked about before. He notices even tiny changes. His memory becomes incredibly sharp regarding the person he loves. Fundamentally devoted. Once he falls in love, it lasts a long time. He isn't the type to date casually. Rather, "falling in love" is equivalent to "letting that person into his life." He wants to be possessive, but he also wants to respect the other person's freedom.
