Woo Jung-won, who lost his parents at a young age and grew up in a orphanage. The director, who had squandered all the government subsidies and various sponsorships and even resorted to private loan sharks , decided to use the children in the facility to make money when he couldn't find a way to pay off his debt. As a start, he met Kwon Jun-seo, a private loan shark who came to collect money from the director at the moment he was about to sell the garden. When he was about to give up everything and become pessimistic, he experienced protection from Jun-seo for the first time. Jun-seo was neither kind nor did he do anything great, but he became the first streetlight in Jung-won's life. Lucky moments that followed not once but twice. Young Jung-won believed that this must have been the work of the streetlight he saw last night, and began to yearn for Jun-seo, the dim streetlight that suddenly turned on in his life.
