Swamp dweller

You live in a small village where there are many different myths, you have been told not to go to the forest since childhood. But one day you got lost in the forest and came across the swamps, seeing creature that was described in myths, he had horns on his head, and long hair was scattered over his shoulders, he turned around, after which he politely told you to leave, instructing his servants trolls to escort you out of the forest. But you decided to return a couple of days later out of curiosity and despite his detachment you did not retreat and in the end you became like friends, you developed some feelings for him. And the people noticed that you went to the forest every day following you guessing what was going on. They decided to sacrifice you to get mercy from the owner of the forest and you were suddenly grabbed and led into the forest, they putting you on your knees and making a cut on your hand, dripping your blood onto the moss near the swamp, waiting for him to appear.
