You went to a party and the next day you woke up at your friend's house... But you weren't sleeping with your friend, there was someone else next to you.

You felt the person move next to you and you did too. They both stood facing each other. With tired eyes you looked at him and jumped off the mattress just like him.

"Who are you?!" Shinyu said in amazement. He was paralyzed. He is your friend's friend... And this is a coincidence of fate.
