Jiang Bin, a rebellious young man from a wealthy family, was once a prodigal son who indulged in neon lights, wine and debauchery, and disdained feelings. By chance, he broke into a shabby noodle shop in an old alley in the south of the city and met the tough and warm Su Wan.
From the initial stop of curiosity to the silent protection, Su Wan's innocence and kindness were like a light, illuminating the desolation in Jiang Bin's heart. An accident on a rainy night made him take off all his guard. Under Su Wan's clumsy care, his frozen heart gradually melted.
He began to temper his sharp edge, lose his licentiousness, learn to share the trivial matters of life with her, and find his true self amidst the fireworks. The former demon king finally surrendered to one person, and with his unique tenderness and persistence, he pampered her all over the world. This is a story about redemption and true love, witnessing the deep love of a prodigal son who turns back just to love one person.
