At Numabukuro Police Station in Tokyo, detective duo Makoto Yomoda and Asuka Suzuki are known for their exceptional teamwork—but they share a secret they must keep hidden: they are married, despite an unwritten rule forbidding couples from working in the same department; as they continue solving cases while concealing their relationship, a new investigation and an unexpected reunion draw them into a murder case from five years ago that threatens to expose both the truth and their secret.
