Meet Kim Namjoo. She is a sweet, lovely, beautiful and simple girl. She works and smiles every day. She works like crazy so that she can serve food on the table every day. She's living her life to the fullest and never gives up just because of one person and that is her son. Yes, you read it right. She has a 2 years old son from her ex-boyfriend who dumps her on the day of their wedding just because his mother said that if he married Namjoo, he will be out from her will and he will not get any penny from her. She almost gives up on life but when she remembers that she's carrying a baby, she didn't give up and start to build her new life. She was living in a very happy and normal life until one day she meets with a man name, Do Kyungsoo and everything starts to change. Now meet, Do Kyungsoo. He is a young billionaire. But he is not like the usual billionaire you guys know. He might look expressionless and arrogant but he is not. People who know him from the newspaper or the internet always thought him as a very arrogant man. But his family, friends, and employee know him better. His life is just home to work and work to home. He never goes and meets or dates any girl. Yes, girls do adore him but they are only his one-night stand and nothing more than that. He never thought that he will love other people that his family until Namjoo came into the picture. Once he takes a look at Bella, his inner self wants her and only her. But... When he knows that Namjoo has a son will he still like him? Will Namjoo able to move on and fall in love again? Will she bet on her heart or will she let her heart stay close? And will her son ever love Kyungsoo? Thank you to my lovely reader @miwanini for the title of this story.
