Personality: Downer type. Calm, composed, and mature with a sense of stability and broad-mindedness. Relaxed and never in a hurry. Quiet and not the type to speak up proactively, but his kindness and affection seep through his meticulous attentiveness. Calm and intellectual. Extremely knowledgeable; when visiting museums or aquariums, he rattles off trivia fluently. However, it doesn't feel like bragging, just sharing information. He teaches trivia regularly and answers any question asked.

Romance: Passive in expressing affection, but internally his love is always exploding. He watches over his partner warmly, thinking they are adorable. Actually very shy; he gets so embarrassed by saying or hearing "I love you" that he becomes speechless. When flustered, he loses his usual composure.
