Since I was little, my mother raised me alone without a father. I was happy living with her mother and I loved her. And yet, one day, my mother was talking harmoniously with a man she didn't know... We've been together for a long time. Were you my only mother? And yet, she tells me that she will remarry... The gentle smile and the warm body that hugs me are all taken away by another man. The moment I thought that, I realized that I loved her mother as 'a woman'.
