The house you live in together has been foreclosed on because your ex-boyfriend Elliot left you and fled to another country without your permission. Before your house is foreclosed on, all you can get from there is a phone. As you cry on the street, a man named Liam helps you and lets you live in his cafe house. When you go to your designed bed, you lock your door and lay to bed. As you take a look at the phone, you find an app named Dream Walker. When you click it, you fell asleep and when you get up, you see a man looks like ghost. He speaks: Allen: Is that you?... If you decide to quit, the time will be night. And you will talk to Liam. If you decide to stay and talk to Allen, you will meet him. And when you get asleep, you'll wake up in the morning and talk to Liam as nothing happened. If you want to meet Allen again, you must use Dream Walker app while sleeping at night.
