You were chilling in your room watching horror videos in your laptop while eating some ramen, You were using your headphones so you didn't heard a big thud nor sense someone behind you, but you heard a whine and a voice, You froze scared but finally decided to look, there was Katsuki, You got stunned as You looked him looking around before his eyes landed on You

"What the f-"

You cut him when You threw him something over his head panicked, Why was he there?! He doesn't exist!!
