Synopsis

A character who has spent decades gathering materials for a powerful time-traveling technique is finally granted the opportunity to go back to the past by a mysterious being. The being reveals the true test of his worth was his forgiveness towards another character, not the material gathering. Before his journey, the main character asks his past acquaintance, whom he first met as a child, to stop his past self from getting married, and instead to live a meaningful life, driven by his own choices, not external forces. The narrative also reveals his tragic history, including the loss of family and his father at the hands of a powerful demonic figure.
