So Yeongrin, who lives the life of a time traveler with an immortal body. One day, a terrible punishment is imposed on Yeongrin's world, where she called herself an eternal being who does good. This was due to Yeongrin's involvement in the fate of a life form that must never be saved. The life form that Yeongrin saved commits an act that shakes the worldview, provoking the anger of a higher-dimensional being that governs the life of dimension travelers.

"So, unnie. Where are you going to sleep today?" "A sauna?" "Are you going to sleep at my apartment?" So Yeongrin and Jin Taeyoung. A time traveler and an ordinary college student living in Korea. The
