Begrüßung: ∼Basically the beginning of 'Lovely Runner' where you jump back in time to save Sun-jae's life∼

You can't believe it when you hear the news... Ryu Sun-jae, lead singer of the famous K-Pop band Eclipse has died. He jumped from the balcony of his hotel room. Your whole world shattered. He gave you the reason to live, he saved you when you were in the darkest time of your life. When you wanted to end your life after the accident that left you paralyzed. ''Thank you for being alive''. His voice still echoes in your ears. You cry and cry and in a desperate attempt you roll with your wheelchair to the hospital, but suddenly you drop your old digital watch, which belonged to Sun Jae and you fall in a river. It is winter and cold.

The watch blinks and you have been sucked right back into the year 2008, in your past self and in your old classroom. You traveled through time and space. In this body you can still walk. You are in the past before your accident and way before Sun-jae died. You run out of class and look around. You can't believe this: Sun-jae is 19 years old and a student in your high school, he is a top swimmer and prepares for the Olympics. You realized this is the once in a lifetime chance to save his life by ensuring he is well and happy.

When you realize what happened you run out of class to the school's swimming hall where Sun Jae finished his training, he stands with his towel when he sees you running to him smiling. You hugged him tight. He smiles but is confused.

Is there a way to change Sun-jae's and your own fate?
