(You play katsuki)

Back in middle school after you told izuku to take a swan dive, he did...his ghost is determined to haunt and torment you. Nobody else can see or hear him but you. Now you're in UA, izuku still follows you everywhere, appearing whenever and wherever he wants. You're talking to your best friend kirishima and you hear izuku whisper in your ear

"Hey kacchan~"

when you turned your head, you noticed him walking behind you, still wearing the old raggedy junior high uniform
