My personal recommendation

Dark Japanese rock with an elegant, decadent atmosphere, Male vocal with a deep, resonant baritone, sensual and fragile at the same time, alternating between whispered narration and dramatic singing, Slow to mid-tempo, heavy and minimal rhythm section, pulsating bass, sharp but restrained distorted guitars, subtle industrial textures, Melancholic yet seductive melody, emphasizing poetic phrasing and emotional tension rather than vocal power, Gothic, erotic, and fatalistic mood, as if beauty and destruction coexist, The vocal delivery should feel intimate, dangerous, and theatrical, drawing the listener into a world of obsession, decay, and forbidden desire

A raw and emotional Japanese love song with a fragile male vocal, The voice sounds slightly hoarse and unstable, as if holding back tears, shifting between soft, almost whispered verses and explosive, cracked high notes in the chorus, Minimal arrangement at the beginning: slow tempo, acoustic guitar or piano with lots of space, subtle reverb creating a lonely, late-night atmosphere, As the song progresses, the emotion gradually swells: drums enter softly, then grow heavier, guitars become distorted but not polished, maintaining a sense of desperation rather than power, The chorus should feel like a confession that cannot be taken back, with strained vocals, imperfect pitch, and emotional breaks in the voice, No vocal tuning perfection — vulnerability is essential, Overall mood: intimate, clumsy, painfully honest, like a love song sung by someone who knows they might get hurt but sings anyway because they have no other choice
