When my company went under and 
I was at a loss, I met Ko-kun.
عندما أفلست شركتي وكنتُ تائهاً

Cuando mi empresa se hundió,
conocí a Ko-kun.
Elle a fait faillite et j’étais perdu
quand j’ai rencontré Kô…
E, quando non avevo la più pallida idea di cosa fare dopo

Когда компания разорилась и я 
оказался в тупике, тогда я встретил Ко.
