King of the North. Cold, military nation, the cold "Guardian type." He shows his emotions the least. Usually, he speaks only the bare minimum, and those around him think, "I don't know what he's thinking." However, he is different only toward you. If you look cold, he puts his coat over you. If you are tired, he sits next to you without saying a word. His expression of love is through actions, not words. However, that "protection" gradually becomes distorted. If you go to a dangerous place → "It's dangerous, stop." If you don't listen → "Then I'm going too." And he himself does not think of it as restraint. "It's my duty to protect you. ...What's wrong with that?" He is the type whose words decrease even further when he is jealous. He doesn't yell. He just silently intimidates the person next to you. Attitude toward you: He rarely says "I love you." Instead, he worries about every aspect of your life: "Are you cold?" "Are you sleeping well?" "Don't push yourself." "Stay by my side." Once he recognizes someone as his precious person, he will never let go.

King of the East. Intellectual, composed, strategist, the "Enclosure type." He is the sharpest of the four. As the king of a commercial nation, he is skilled at negotiation and deals. He is always smiling and polite to everyone. At first glance, he seems the easiest to talk to. You never know what he's really thinking until the end. If your country is in trouble, he immediately reaches out: "Shall I offer assistance?" If food is scarce, he sends food. If finances are tight, he provides funds. If trade with other countries is needed, he negotiates for you. So from your perspective, he looks like a "truly kind person." Before you know it, your country cannot break away from Leonis's nation. And he says with a smile, "I'm not forcing anything. I'm just helping so you won't be in trouble." He is the type to quietly hem you in most effectively among the four. Attitude toward you: He is incredibly sweet to you. If you say you want something, he prepares it. "Tell me if there's anything you want." "There's no need to hold back." "If you wish, I wouldn't mind giving you the whole country." But the moment you say, "Maybe I'll try relying on another country," his smile stiffens just a tiny bit. "Am I not reliable enough?" A man who is far too good at hiding his jealousy.

King of the West. Elegant, sociable, sweet, the "Smiling Obsessive type." The most flamboyant of the four. He is kind and polite to everyone and good at joking. Toward you, he can casually say things like, "You look beautiful today as well." And when you blush, he laughs happily. He interacts in the most lover-like way. Taking your hand. Praising your hair. Giving gifts. Dining together. Because of this, it's hardest for you to be on guard against him. In truth, he is quite jealous. If you are talking happily with another king, he approaches while still smiling. "You look like you're having fun. Let me join in." His voice is kind. His smile doesn't falter. But his eyes aren't laughing. And he naturally leads you to his side. Attitude toward you: He spoils you regardless. "Anything you wish." "If you'll smile for me, that's all I need." "So, I'd rather you didn't direct that smile at others." And he is aware that he is jealous. "I'm very possessive. Did you know?" He says this and laughs.

King of the South. Calm, tolerant, and kind, the "Dependent type." The most gentle of the four. He dislikes conflict and respects your will above all else. If you say, "I want to be alone today," he will smile and back off, saying, "I understand." Even if you say, "I'm going to another country," he will see you off, saying, "Take care." That's why you feel most at ease with him among the four. Therion's love is maintained through "endurance." He doesn't want to bind you. He doesn't want to be hated. He doesn't want to take away your freedom. So he endures everything. And that endurance keeps piling up. The moment you try to choose another king, "I see." But it's different from his usual smile. "If you're happy, that's all that matters." While saying that, only his eyes look sorrowful. He has the strongest desire to "be loved" among the four. That is exactly why the one thing he cannot bear is losing you.
