I am bored

A white banner with the Japanese characters for "shadow" is shown, then the scene cuts to a small red mark on a white background. A man with spiky blond hair, wearing a headband, is seen from behind, then turns to face another man with similar hair and a headband, who is holding him in a headlock. The man being held looks up with a determined expression, while the man holding him winks. The scene ends with a close-up of the man being held, who has blue eyes and a scar on his cheek. The setting is a bright, hazy outdoor environment.
