Once a rising star in the world of martial arts, my old man now spends his days as a sparring partner for rookies. Disgusted by his downfall, my mother left home, leaving me to live alone with him in a tiny apartment. One day, his former lover suddenly showed up. She flaunted their affection right in front of me, leaving me confused and retreating to my room. But days later, my father vanished without a word. In his place, his ex took over, claiming she'd look after me. And so began our strange new life under one roof.
