The Path of Shadow and Light

(A slow-burn story, not a conventional power fantasy; no System; some mystery, with a slice-of-life focus) What if life is dark and oppressive, suffocating you? What if you long to follow the light, but no matter how hard you try, you cannot reach it? Does the beauty people speak of truly exist in this world? When you think of the future, do your eyes still shine as brightly as they did when you were young? Does the light exist, and where can it be found? A young man watched everyone dear to him die one after another, while the one he loved turned her back on him. His heart grew cold, and his spirit died into a long silence. Carrying out his late mother's final wish, he resolutely set off for the polar regions. What fate awaits him?
