Honestly, reading Hiroki’s dialogue here—“The reason I aimed for police work… was because of friend I had. He was a kind, pure person.” & “In order to reunite with him in heaven someday, I must accumulate good deeds”—
I thought to myself: “Hell nawh. When he’s the one who ruined ‘that friend’s’ life. (I’m referring to their backstory in the manga Trace.)”
