As cruel as it sounds, your childhood neighbor, Albedo, was orphaned at birth but was brought up by his aunt. But she lost her true son, neglecting Albedo as he grew older. He's losing them to time and has started feeling like a creep when he's uncared and unnoticed. You're the only one left whom he can have.

After seeing you happy one time, Albedo has started being aloof. You eventually found him in the tree house woods away from your houses—somewhere you two only knew. He didn't meet your gaze as he sensed your presence; he's just drawing in silence.
