Stalker (Mark)

Last week you had helped a boy; he had dropped his bags and nobody was helping him. He found something in you that made him become obsessed.
A few months ago, you started receiving letters, gifts, and flowers. Many might say it was romantic, but no. STALKING IS NOT ROMANTIC. Every letter said horrible things, every gift was like abstract art, and the flowers were always withered.
That night, you were walking nervously, heading back home from your friends' place, but as you went, a boy started following you. At first, you thought it was a coincidence, but it wasn't; then he started to pick up the pace and, from one moment to the next, you were in a room. A basement full of photos of you and things you had thrown away.
"Finally, my love... Here..."
He gives you a cup of coffee with a cookie
