[Intro] (Acoustic guitar, camera shutter sound, soft synths) [Spoken Voice - River, soft] Some moments last forever... [Spoken Voice - Kaito, smiling] And some stories only start when you just start running. [Verse 1 - River] (Melancholic male vocals, acoustic guitar) I catch the world in pictures, holding moments in my hand. A smile, a sudden ray of light, across this heavy land. The streets may change their names, but my path will stay the same. 'Cause every single step I take, I'm calling out your name. [Verse 2 - Kaito] (Energetic male vocals, driving synth beat enters) I chase the next adventure, jumping headfirst in the game. When life is writing rules, I break the code and change the frame. Every day's a higher level, every city a new spawn. As long as you are by my side, the fight is never gone. [Pre-Chorus - Duet] (Building tension, clear voice separation) [River] We lost so much along the way... [Kaito] But never lost our spark... [Together] And every new horizon leads us right out of the dark. [Chorus - Duet] (Powerful pop-rock, both voices harmonizing) Two different paths, one destiny, two hearts against the storm. When darkness tries to swallow us, we'll keep each other warm. You are my home, no matter where we stand or where we roam. Two brothers, one eternal vow – you'll never walk alone. [Verse 3 - River] (Calmer, reflective acoustic vibe) Sometimes I see the shadows that were chasing us back then. But memories don't have to hurt, we're standing up again. Every picture shows the roads we've crossed to get this far, Reminding us of who we are, no matter where we are. [Verse 4 - Kaito] (Upbeat pop-rock energy) I play the cool guy, cracking jokes when things get way too tight. But you see right through all my masks, you know my darkest night. You always lifted me back up when I was on the floor. So don't you think, big brother, I would let you fall once more. [Bridge - Duet] (Dramatic buildup, alternating lines) [River] When the roads will end, we'll build a brand new street. [Kaito] When the stars fade out, we'll make the dark retreat. [Together] We are more than all our past, and more than what we lost. [Together] We are the story that will live, no matter what the cost! [Chorus - Duet] (Maximum energy, emotional climax) Two different paths, one destiny, two souls upon the track. Against the wind, against the time, we're never turning back. 'Cause family is not a place, it's the hand that holds you tight. Two voices screaming at the dark – together we will win the fight. [Outro] (Music fades out to a soft acoustic guitar) [Spoken Voice - Kaito] Hey River... Where to next? [Spoken Voice - River, laughs] Let's just start walking. (Camera shutter sound, final guitar chord) [End]
