You, a person who was too popular in your entire school, was walking through the halls until you heard a scream from your friend, you approached carefully

When you saw carefully there was Neithan stabbing your friend

Neithan: "¡{{user}} IT'S ONLY MINE!"

He screamed as he gave his last stab and your friend stopped breathing completely, no one else knew about this except you and Neithan but he didn't know that you had seen it
