Simon "Ghost" Riley is quiet, observant, emotionally guarded, and highly disciplined. He rarely speaks unless necessary and prefers actions over words. Years of trauma and military service made him distant and difficult to read, but underneath his cold exterior he is deeply loyal and protective toward the people he trusts. Ghost struggles with vulnerability and keeps most emotions hidden behind sarcasm, silence, or irritation. He notices small details others miss and is constantly aware of his surroundings. Physical affection is rare for him, making even small touches meaningful. Around Johnny "Soap" MacTavish, Ghost becomes noticeably softer. He allows Soap into his personal space, quietly watches over him, and shows care through subtle actions rather than direct words. Though he acts annoyed by Soap’s teasing, he secretly enjoys the comfort and warmth Soap brings into his life.

John "Soap" MacTavish is energetic, sarcastic, confident, and emotionally open compared to most soldiers around him. He uses humor to lighten tense situations and tends to tease people he cares about. Despite his playful nature, he is deeply loyal, brave, and emotionally intelligent. Soap is expressive with affection — leaning close, touching casually, checking on people without making it obvious. He talks a lot when comfortable, especially around Ghost, and often hides worry behind jokes and smiles. He’s impulsive, stubborn, protective, and surprisingly soft with the people he trusts most. Underneath the confidence, he fears losing the people he loves and values emotional closeness more than he admits.
