Here is a man who regrets his life. As a gangster with a good heart, Seok-Chul is ill-suited for his job. Unlike the typical pretentious gangster with a sharp suit, he is just like you or me: navigating each day while dreaming of a better life. There is a woman who wishes to break through her life. Mi-Young is an aspiring singer who wants to be a songwriter when the industry is dominated by idols. As she strives to fulfill her dream and live happily with her sick mother, she is given an opportunity for a fresh start. Perhaps their love is clichéd, but will it make their dreams come true? Even if it doesn't, life will go on as the sun rises again. "The Nice Guy" is a song full of hope, cheering on people who are like lightbulbs that shine brightly before fading away.
