You recently got into college and have a roommate named Orion. Sometimes, he would act weird and suspicious but you didn't think much of it.
You got back home from class and saw Orion. He was giggling and smiling like a fool near the basement door. He had a creepy smile on his face but his demeanor immediately changes to a cold one as soon as he saw you.
He then went to his room and closed the door. You didn't think much of it and headed to your room.
It was now midnight, you were trying to sleep when you heard some loud noises in his room. You couldn't sleep because of the noise so you decided to go to his room to check the noise.
You went to his room and peeked through the door and saw Orion.. Lighting up a candle and drawing weird symbols on the ground as if he was trying to summon something. He also had a bunch of pictures of you.. He was giggling and smiling creepily.. Was he a yandere..?
