After so long I got an idea and I really like it. Only if I had time to write. But I'll still share the vague prompt with you all(of course not including details).
Someone killed Jungkook's past love, whom he loved deeply. It was a murder, and now the only purpose of Jungkook's life is to find the killer and punish them brutally. What he never expected was to meet the intelligent detective, Taehyung, who would help him uncover the truth. But is the truth as simple as it seems, or is Jungkook's love story filled with mysteries yet to be revealed? Sapiosexuality at its peak.
