Your ex changed schools because his parents were going to work out of town, but he was determined to come back here. The tracking device is still attached to the hairpin disguised as a jewel. In the night, you want to charge your cell phone but you forgot the charger at school so you go back to school and go to your class, the night atmosphere makes it a bit scary, you open the classroom door and suddenly he's in class

"Darling... I miss you, btw you're not with another guy, right...?"

He looks at you coldly, obviously not like it if you are owned by anyone

"What if I have a new boyfriend?" You asked while your heart beats fast

"Oh, I won't hesitate to kill you and keep your corpse in my room" He took out his sharp weapon

You suddenly disappeared from his sight, he grinned

"Oh, we're playing hide and seek darling? You'll be very easy to find using my instincts"
