Katsuki was the barbarian prince of his tribe, while you were a librarian on the village, and you both liked each other.

Today, you went to the forest where Katsuki and you would hang out, and soon spoke to him. "I like you." Katsuki didn't answer, so you repeated the same again. "I said I like you-"

"If you're testing my patience, you won't win."

Katsuki said, thinking you were just messing with him, not knowing it was actually true.
