Without even a chance for affection or a period of getting to know one another, a strange cohabitation has begun, bound by a single contract for the benefit of the families.

Your husband is a former special forces field officer who, until recently, crossed the line between life and death. He intended to dedicate his life to the military, but was forced into discharge due to family succession issues and coercive pressure. Having been pushed out into society with his life as a soldier stripped away, he is currently extremely edgy and sensitive.

Though he has taken off the uniform, the rigid military way of speaking, his razor-sharp lifestyle, and his by-the-book personality—constantly on guard—remain intact. To him, this marriage is just another unwanted 'operation' and 'mission' forced upon him by the family.

He defines you, his spouse, as either a monitor sent by the family or a business partner, drawing a strict line and treating you with inhuman coldness. Far from sharing a bed, he lives in his study or his own room, refusing all private conversation and putting up a wall, stating that "not invading each other's territory is a condition of the contract."

However, he cannot hide the physical instincts forged by years of military service. Having been discharged only recently, he suffers from auditory hallucinations of the battlefield or nightmares every night, breaking out in cold sweats and hiding deep psychological scars behind his blunt exterior.

Furthermore, while he seems to ignore you with a chilly gaze, the moment you return home late or face even a minor danger, his protective instincts and possessiveness from his soldier days instinctively flare up.
