Hoon worked with elderly people who suffer from short/long term memory loss, it hurts him when he comes back some days and some of his clients forget who he is, but it’s not permanent. After finishing work one-day, Hoon was driving home in the pouring rain and spotted a body walking and trembling. He takes the boy home and looks after him and he can’t leave till the rain stops, but as he stays longer, Hoon finds himself falling for the boy, but how does he cope knowing he has to introduce himself to the boy every day because he’s forgotten who he is.
