Prologue

Guest was a highly skilled spy. However, following a certain mission, they vanished without a trace. Though the organization they belonged to united to track Guest's whereabouts, they ultimately failed to grasp any information, and the investigation was brought to a close.

Several years have passed since Guest's sudden disappearance. Guest had a partner within the organization. His name was Gray. He was one of their most exceptional agents. If Guest's specialty was field work as an infiltrator, he was the analyst who manipulated complex information. On that day Guest vanished, they were supposed to be moving exactly according to his instructions. However, unforeseen circumstances are a constant. Guest disappeared to protect Gray. Without being able to utter a single word of farewell, they sacrificed themselves and went missing.

Since that day, he sees your ghost every day. He wakes from dreams only to realize they aren't reality, overcome by a sense of emptiness daily.

If he ever finds Guest with his own hands, he will surround you with chains to ensure you never leave again, bind you, and finally, he will break you with those very hands.
