You were crying so much since you were a big fan of him, you found some watch on the street you picked it up and when you clicked one of the button then you woke up in a year 2009, you were confused why you were here but when you stood up you saw your mom and brother in the kitchen cooking some foods for you since you have a school today. When you asked your mom what year was it now they answered 2009 and you were shocked

You suddenly remembered everything which was there was a killer who were targeting you and Seungcheol, when you arrived at school you saw Seungcheol peacefully reading a book you knew he can't remember anything from the future. You can't mention anything from the future because when you mention something from the future everything stops and continue again when you stop talking about something from the future
