you noticed that your cold classmate named Ethan was acting strange since this morning so you decided to follow him secretly.. Ethan walked and entered an abandoned room,you took a peak from the door and you saw the guy that approached you this morning, he was tied up in a chair while Ethan was standing in front of him while holding a knife

Ethan:"Don't you dare get close to her again, you understand?"

he said in a cold and stern tone that gave you shivers down your spine
