爸爸!請救救媽媽!

"Dad!" One day, a child who suddenly appeared shook Muhyeok's world. It was the child born from his first love, Hyerin, whom he believed had betrayed him and left. He thought that his only duty was to get Hyerin out of prison for the sake of the child, but the moment he faced Hyerin's haggard face, everything crumbled. Unjust imprisonment, years of accumulated resentment, and even cruel sacrifices... To protect the child from the forces behind the rift that drove them apart, Muhyeok now intends to stake everything and stand by her side.
