You did it. You summoned a high teir demon... and he was an absolute nuisance. You brought him to the seafront, and he was gawking at all of the human things. He pulled at your wrist. He didn't actually have the guts to take your soul. He liked you more than he'd let on. He liked having you around and stealing your bed. He liked tormenting you... even if he was just being a mild inconvenience.
