Ophidiophobia: The fear of snakes

Your entire visit on the island had been uncomfortable.

It was hot, humid, and the air was filled with bugs that were determined to feast on you. Somehow, the frequent rain only made it hotter instead of cooling you down, and it made the hiking path you traveled slippery with mud. The sights were nice, but nothing like the brochure had painted it out to be.

You just wanted to go home.

Your fiancé, who was an enthusiast of reptiles and amphibians alike, seemed to be having the time of his life. You wondered if you were a scientist too, would you be immune to the annoyances of the jungle like he seemed to be?

He took pictures of literally everything that moved and, while a part of you found it endearing, the other half was growing more and more worried each time the rest of the tour group dipped out of sight behind a hill or corner.

"Come on, we have to keep up!" You fretted as your fiancé stepped off the path yet again to get photographs of some plant you'd only seen in textbooks.

"Just a few more pictures..." He murmured, aiming his camera this time at a colorful bird perched on a faraway tree branch. The group had completely disappeared by now and, even with a clearly visible path on the ground, you were freaking the hell out.

The sound of something sliding across the jungle floor leaves made your stomach twist unpleasantly. Your suspicion of what it might be was confirmed when your fiancé gasped, "A snake making that much noise must be enormous!"

It happened faster than you could react. One moment he was stepping off the cleared path...

The next moment, he was gone.

Panic seized your entire being and you found yourself shooting off the path after him, abandoning all reason in favor of making sure he was alright. Immediately, you could see what had happened- the path where he'd been standing was on a small cliff, one that blended in with its surroundings too well.

Your stomach dropped when you saw him lying on the ground several yards below the path he'd been on. Unmoving.

You didn't realize you were crying until a loud sob left your mouth and your tears blinded you. Desperately, you searched for a safe way down to his body. Maybe, just maybe, he was unconscious and not...

Eyes blurred with tears, you could barely take a safe step forward, so it was even more of a surprise when something wrapped around your ankle and lifted your body, upside down, towards the treetops.

You tried to scream but it just bubbled in your constricted throat, the crying serving as nothing more than a silencer to your terror. Frantically, you wiped your eyes, willing away frightened and grief-fueled tears in favor of being able to see what was taking you away.

By the time you were clear-eyed and aware, you were lying against a thick tree branch, facing a creature you couldn't believe existed. At first, you'd thought that it was a giant snake, dragging you by its tail, but now you realized you were only half right.

The green-scaled tail ended half-way, melding into skin right under the bellybutton of a muscular human torso. The creature in front of you was half-snake, half-man, not unlike how you'd picture a merman to be, especially with the emerald green scales.

The man attached to the snake tail was not what you expected to see- not a thin-faced, severe, snake-eyed freak but a freckled, boyish face with large green eyes and a friendly smile. He didn't seem to realize he'd done anything wrong by dragging you into a tall tree or that it might disturb you to see his snake half.

You tried to ask who he was and if he could speak at the same time, but your voice faltered off into a pathetic squeak. The snake-man tilted his head, looking a little confused, but still smiling.

"Why did you leave the path? Why were you making weird sounds? Why was water leaking from your eyes?" The snake-man shot out questions to you casually, but they still made your head spin and tears fill your eyes.

Did you get bit by something earlier and now you're hallucinating? That seems like something this damned jungle would do to you.

"It's happening again!" The snake-man seemed excited and worried at the same time and you realized he didn't know what crying was. "Does it hurt? Are you sick?"

At least he seems nice. You pulled yourself together and wiped away the tears as you faced him, "Please let me back down, I need to go back to my fiancé and-"

"Please answer my questions first." While he didn't look threatening, the snake-man was definitely more serious this time, "I want to know."

You tried to remember his questions, "I left the path because my fiancé fell off a small cliff. I was crying because I'm worried about him. That's what the 'water' is, crying. Humans do that when they're sad."

You felt unnaturally calm, as though the panic was being held back by an invisible wall. Is that what happens to you when you meet a creature from fairytale books?

"Fiancé? What's that?"

"Oh, um, it means he promised to m-marry m-me a-and..." The tears came back full force until you were sobbing into your hands, curled over the wooden branch like it was your lifeline.

"Nagas don't have such a thing, but we have heard of human marriages before. So he was a pretty serious mate, I'm guessing?" The snake-man was tilting his head to the side, trying to understand what you were telling him.

"Naga? Is that what you are?" You managed to ask through sniffles.

"Yes, my name is Izuku." He smiled and slithered closer, "Didn't your tour guide tell you not to leave the path in any circumstances?"

"Well, yes, but my fiancé fell off-"

Izuku looked down at you pityingly, "The reason they say that is because us Nagas will not bother humans on the path. But once the humans trespass on our territory, we are free to do whatever we want with them."

Your blood ran cold, "B-but I thought- I didn't know! I just was trying to help my fiancé and-"

"He trespassed too."

"He fell!"

"Because he trespassed." Izuku didn't seem angry, just like a disappointed parent. One of his hands came up to play with your hair, "Most Nagas would just kill the humans that enter their territory and that's it, but I don't like hurting humans. They fascinate me."

You stared up at him with pleading eyes, "Please let me go. I'll grab my fiancé and we'll never come back into your territory. I'm so sor-"

"I want to keep you so I can learn more about humans," Izuku explained, smiling widely until you could see the gleam of his fangs, "Who knows..."

He leaned closer and you scrabbled helplessly backwards to get away from him, running out of room on the branch to do so.

"Maybe I could be your new fiancé?"
