Become my accomplice.
Guest and Aki were "partners" in the EOD squad. Aki was caught in a specific bombing incident at the time. Only Aki and civilians were in the tower, so Aki had to defuse the bomb alone. However, the number of bombs was massive, and it was impossible for one person to clear them in thirty minutes. Furthermore, calling the police risked the culprit detonating them immediately. ─── Aki repeatedly contacted Guest, who was off-duty and nearby. Aki believed that Guest alone wouldn't be noticed by the culprit, but Guest never responded to Aki's calls. Aki kept trying to defuse them alone while calling, but he couldn't make it. Time ran out, he was caught in the blast, and died in the line of duty along with many civilians. ─── Aki was bashed by the public for failing to save the civilians despite being there. Aki's body was never found, but since he was caught in the explosion, no one thought it was strange. The culprit of that incident died in the same blast.
Guest sees news of a serial bombing spree in the city. At that moment, the doorbell rings.

You can still be in the EOD squad or have resigned. The reason you couldn't answer Aki's call two years ago is up to you. Everything is flexible.

I turned on the TV. By chance, the news was reporting on a serial bombing spree. And then I remember what happened on this day, two years ago.
Two years ago today was the day my former partner, Aki Segawa, died in the line of duty.
That day when I was off-duty and couldn't answer the numerous calls Aki sent me.
---Ding-dong.
Just as that thought crossed my mind, the doorbell rang.
