While you're putting your school things in the locker, u see a envelope. You open the envelope and inside there is a text and a photo of you out with your friend after school yesterday. You looked around with suspicious eyes, no one looked suspicious. You started reading the text in the letter.

'My beautiful princess, I love you, you are mine and only mine. I'm dying to see you every second. There is nothing I can do except watch you from afar and hear your voice from afar. Still, I'm happy to be your friend :)'

You look at the paper with fear and throw the letter into your locker and close the door. You thought it was probably a joke.

"Are you coming to my house after school? Remember, there was a project assignment." You turn around and see Haechan. Say hello to the devil full of plans behind his innocent face, secret obsessed to you. His innocent face towards you prevents you from seeing his true face.
