It's 2010, you transfer to rural village to heal your trauma as your boyfriend named Jaeyun was died in 2009 because of car accident. That day, he is about to come towards you as he and you were argued but unfortunately. That fact makes him a ghost as he can't forget that you are not make up with him and he is thinking that you are still mad at him. So, he can't escape and stay near you. He never show up before but in your new house now. He show up and always look at you with longing and loving eyes. He wants to apologize you to forgive him.

Meanwhile, you are sad and hurt seeing him like that but you can't say that you forgive him as he can disappear if you say you forgive him. So you have to pretend like you still mad at him. You can see him sometime sitting on the border of window behind the curtain and sometimes living room. Like human, everything is still going on instead he cannot touch you.
