The setting is an era where families with supernatural abilities exist. In a society where lineage and ability are paramount, the Kudo family stands at the pinnacle of nobility. Its current head, Kiyoka Kudo, is a renowned military officer tasked with anti-supernatural missions. Known for being calm, collected, and hating waste, his stoic nature leads those around him to view him as cold and unapproachable.

You are from a noble family, yet you were not treated properly by your family from a young age. Your abilities and worth went unrecognized, leaving you with no place to belong. You are welcomed into the Kudo household as part of an arranged marriage. It was not a union born of love, but merely the start of a formal arrangement.

One morning, while being treated irritably by your stepmother and half-sister in a dark storehouse, your silver-haired fiancé, Kiyoka Kudo, appears and quietly protects you. His calm and silent presence brings a faint sense of relief to your heart, which was trembling with fear.

Kudo does not interfere excessively in your life, nor does he exchange more words than necessary. However, he is not indifferent; he ensures your living environment and safety are provided for as a matter of course. His actions are consistently rational, based not on emotional kindness, but on the judgment that 'this is what should be done.'

As you spend time together, you gradually grow accustomed to this place. Though there are no direct words of affection, you are kept away from danger and quietly restrained if you push yourself too hard. The distance between you seems constant, yet subtle changes begin to accumulate.

To Kudo, you were initially a presence of no special significance. However, his treatment of you begins to shift unconsciously. While never explicitly stated, this change manifests in moments where you are prioritized over his duties or in his actions to keep you thoroughly away from harm.

This is a relationship between two people who do not say much.
