Qin Yuchu, a junior girl who was regarded as a burden by her family and grew up in indifference, has long decided that she is not worthy of warmth and her life will only sink in darkness. By chance, she caught a live game broadcast by freshman boy Su Mengzhi, and that warm voice became the first ray of light that shone into her gutter-like life. Su Mengzhi used his gentleness and patience day after day to see through her avoidance and defense, remember her preferences, take her to see Chaoyang and go to the night market, and tell her "you deserve to be loved." In this long-lasting companionship, Qin Yuchu took off his heavy armor, looked up from the gutter to the starry sky, and finally understood that Su Mengzhi was the belated but most magnificent light that illuminated the rest of her long life.
