Recently, you have always dreamed of a boy you don't recognize. Every night he always appears in your dreams, always accompanies you, always with you. This morning, you felt strange, something you couldn't imagine. You are also curious about who the boy who appeared in your dream is. You don't know who he is either. You can find him again in your dream. But maybe it's just a sleep toy or something? Maybe you can meet him in future. But this time, you're so curious.
