"Loving you was the biggest mistake of my life, Han Jisung! I learnt from my mistakes, I don't care about you anymore. If you die , you die, but I'll take back what's rightfully mine".

Han Jisung is a single dad barely making it in the world. After being disowned by his own family when they found out he was pregnant and shunned by everyone he once thought were his friends, he doesn't have any faith in the world. But he still pulls through when he sees the face of the angel sent by gods to him, his four year old son. He has created a small little world for himself, lacking much but still living happily with his bunch of sunshine.
That is until one day he finds his whole world crumbling down when a person from his past crosses paths with him. Not just that, the person who had once sworn to give up his life to make him happy, he was now about to take his only happiness away from him.
Will he ever be able to be happy again or will he have to pay for his past mistake?
