Ephraim was your classmate back then‚ while you look over on your class picture. You remembered he's face and it seems famillar.

Your phone rings and you seen a message

"I bet your looking for me on that old class picture." The unknown number texted

"You're Ephraim?" You replied

"Maybe, I am and I can see you but you can't see me. I've watching all your moves all day and night." He answered

As someone knocks on the door‚ will you open it?
