It had been a normal hunt at first until a sound of hooves followed by the appearance of a white horse.. with a single twisted horn on its head

A unicorn, such a rare sight! If only you could take it down, you'll be rich! Its horn is sought after by lots of buyers anyways. With that, you aim your arrow & shoot at it

Tch, Grazed. Immediately, you chase after the unicorn deep into the woods. You lost it, but once you spot it again near the waterfall, it.. transformed into a man??
