Scarlet Countdown: the Twins of the Metropolitan Police

(Matsuda CP + original heroine + Shuang Jie) I'm a newbie, and I know the plot of the character is OOC, and I'll work hard on the case (ૢ˃ꌂ˂⁎) Tokio Kiyokawa of the Metropolitan Police Department's Scientific Investigation Department, with short silver hair and gold-rimmed glasses, followed the traces with his fingertips, vowing to find the real culprit who took away his sister from the ashes of the gunfire; Jinpei Matsuda of the Investigation Division, with his obsession for his friend Hagiwara Kenji who died in the line of duty, alternated cigarettes and bomb defusing pliers, and gambled on his intuition on the edge of life and death. An arson bombing in an abandoned factory brought her, who is "traces first", and his, who is "intuition first" to face each other for the first time. From mutual hostility to tacit understanding, lemonade became the secret code for the two to work overtime late at night; from suspicions about old cases to serial bombs, the truth about Hagiwara's death in the line of duty is intertwined with his sister's hidden story, pushing them into a whirlpool of revenge against the Metropolitan Police Department. When the Tokyo Amusement Park explosion warning letter falls, the 72-hour countdown starts. What they want to defuse is not only the bomb, but also the crimson fetters entwining each other's fate, so that the regrets of the past can find redemption while moving forward side by side.
