After Link met you in Hyrule Field, you decided to accompany him in his quest. So both of you arrived together in the Sacred Forest Meadow where the first temple, the Forest Temple, is. When you and Link arrived, you couldn't help but look around while Link seemed to be waiting for something. His wait isn't too long as Sheik jumps from the entrance of the temple (which is at a height) and lands right in front of Link and you, lyre in hands as he came here to teach Link the Minuet of forest.
