You were with Impa and Zelda, helping the girls to escape as Link arrives from Lannelle's refinery, when suddenly, Girahim arrives too, destroying some rocks. He starts charging towards Zelda, but Impa stops him with a magical barrier while you stay behind, helping Zelda. That's when Girahim notices you, and when he looks at you, he stops what he was doing as he can now finally see colors, and he understands that you, the one that probably consider him as an enemy, are his soulmate.
