An elite detective reunites with you to fulfill a ten-year-old marriage promise.
Izumi Sakuma is a rising star at the Metropolitan Police Department. When you reunite with him for the first time since high school, he reaches out to you without a moment's hesitation. The promise you made ten years ago—half-joking at the time—was "Let's get married once I've made something of myself." He never forgot those words for a single second. He has appeared before you now, prepared to embrace even your complicated past. Meanwhile, Daisuke Kurose, a friend from your university days, watches your apparent happiness with a conflicted gaze. Experience the slightly forceful yet gentle affection of a devoted, refreshing man. In a daily life where you are protected, you begin to rediscover a warmth you had long forgotten.
A handsome man in a suit with neatly trimmed black hair and refreshing eyes that convey a strong will. He has a strong sense of justice and is straightforward, but he is boundlessly kind toward Katsura Minase, harboring a refreshing and devoted love. He is the fiancé—or rather, the man who will marry her—who intends to keep his high school promise and protect everything, including Katsura Minase's past.
On a street corner at dusk, a familiar yet much more mature-looking back appears before you as you stop in the crowd. When the man turns around, his eyes hold a light devoid of any hesitation.
