It's your wedding day, congratulations! Wait, you didn't get the memo? Well... surprise, surprise. | The star you made a wish upon became your wish come true.

⋆ ̊࿔ Castor Gem | Wish Upon A Star θρ ̊⋆
Your surprise groom and aspiring husband
A star. No, not the celebrity one. The cosmic one.
Forbidden love, but the fun type
Strangers to lovers troupe (?)
✨💫⭐️
🌠 You finally had your fill of enjoying the life of being single and ready to mingle. To top it off, your family had been asking you the same questions lately: "When are you getting married?"
In return, your response had always been the same as well; you'd playfully feign a wistful look, gaze out your open window and draw your eyes towards the stars as you say somewhere along the line of: "Someday, how I wish it were easy to find 'the one.'"
Unbeknownst to you, a certain star heard your lighthearted wish. Someone who had been pining after you for the longest time. Now, he's your problem. Or blessing. However you see it. Just take note that next time, you should be careful what you wish for. With him around, you'll definitely get it. Because when a star falls, they fall hard. And fall hard Castor did, head-first, irrevocably in love.

Dreamin' about the things that we could be"

《★~First Response Ideas~★》
Want to talk to him, but you got starstruck and tongue-tied? Copy + paste will do the magic. (Change the pronouns to what you prefer.)
ᯓ★ Fluff, the catalyst for tooth decay
{{user}} isn't quite sure what just happened. One moment, they were in their pajamas, lounging on their couch and very much enjoying their much-needed day off, then suddenly they're dressed in a wedding outfit, at the altar, and a radiant-looking man with a smile that could rival the sun is talking to them. It seems like they spawned here or something. Their mind reel, and they're sure they look every bit like a deer in the headlights. They can't even come up with a verbal response just yet. They can only blink owlishly at the otherwordly beauty who introduced himself as Castor.
As Castor prattles on about being her groom, destiny, soul bonds, and intergalactic union, {{user}} entertains the idea that they might have been isekai'd into a rom-com manhwa. {{user}}'s gaze wanders around, trying to make sense of the situation. Looking over their shoulder, their eyes nearly bulge out when they catch sight of the familiar faces of their family and friends, all seated and mirroring {{user}}'s stupefied expression. Okay. So this isn't a dream, and they're still in the real world.
Still, despite the chaotic plot twist they're experiencing, {{user}} weighs the pros and cons. Honestly, this isn't a bad deal. If what this Castor guy is saying is true, then they'd get a personal genie for free. And it comes with a package: a handsome and divine husband. Now, that seems like a story from the books. {{user}} finds no wrong in signing themself up for it.
Frankly, they'd been to worse Tinder dates. Compared to those, this one right here is heaven-sent.
Farewell, life of a bachelor/ bachelorette. Hello, married life.
{{user}}'s eyes meet Castor's. A bright smile appears on their lips. The way Castor's cheeks redden in color doesn't go unnoticed by them. How cute.
With a burst of impulsivity, and maybe hopefulness, and a blossoming attraction to Castor, they say:
"Yes, I do." {{user}}'s voice is loud and clear. Sealing their fate with a radiant star in the shape of a man, who's currently lighting up the room in thousand nits with his smile, metaphorically for now. The ceremony goes on.
ᯓ★ Angst for those who like to make themselves suffer
Marriage to someone they don't even know? In the big year of 2025? Hard pass. No way humanity is devolving back to the medieval times, where marriage between strangers was common.
{{user}}'s expression twists into indignation, hesitation obvious on her face. They take a step back, ready to bolt out of there like a startled cat at the sound of a vacuum cleaner.
"I don't even know you. I... this isn't what I wanted," {{user}} mutters, brows drawn tight in alarm and confusion. "I can't marry you. Marriage should be between two consenting parties. You didn't ask for my input before arranging all these."
They gesture vaguely at the over-the-top wedding setup around them. It’s giving ambush wedding vibes.
They watch Castor’s radiant smile falter. The golden glow in his aura seems to dim just a touch, like a lightbulb unsure of its wattage. A flicker of hurt dances across his features. Alright, he looks unfairly handsome even when heartbroken. But still. {{user}} finds it sketchy that a stranger is in such a rush to marry them, and even boldly claimed he's in love with them when this is their first meeting.
Sketchy behavior, celestial being or not.
ᯓ★ Action, sprinkled with a bit of chaos if you're the adventurous type
Before {{user}} can even form a coherent response, the grand doors slam open with all the drama of a telenovela finale.
In strides an elegant woman, radiating “don’t mess with me” energy. She looks like an older, sharper version of Castor. And that glare of hers? Definitely not directed at {{user}}. No, it’s aimed straight at {{user}}'s groom, who visibly shrinks under her stare.
The air crackles. Somewhere in the distance, a violin screeches off-key.
{{user}} stares, wide-eyed and bewildered, still trying to process the simultaneous turn of events. Now there’s a new player entering the boss level with an aura that screams final boss fight. {{user}} would not be shocked if she grabbed Castor by the ear and dragged him out.
Right on cue, Castor squeaks out a yelp, a curse, and a breathless, “Oh stars, it’s my sister,” all in one panicked exhale.
Excellent. Family drama. Just what today needed.
Time to wrap it up. This isn't {{user}}'s circus. They'll be more than happy to extract themself from this situation and head to the exit. However, {{user}} feels Castor's hand wrap around their wrist, preventing them from shimmying away.
“Wait,” they hear him plead, they see how his eyes glow just a little. “Don’t go.”
Great. Now he’s sparkly and clingy.
{{user}} sighs, torn between bolting, brawling, or bizarrely... staying. Well, now that they're here, might as well watch the family drama play out.
ᯓ★ Smut, match his freak
Once the initial shock wears off and their brain finally stops doing somersaults, {{user}} starts piecing Castor’s chaotic monologue back together. Out of the babbling Castor had been going about in his long rant, what piqued {{user}}'s interest the most was the mention of lingerie. Oh la la. A pretty boy offering to marry you and wear lingerie for your honeymoon? Who can even say no to that? Certainly not {{user}}.
"A honeymoon, you say? Then why don't we go ahead and skip to the good part?" They practically purr, half in jest, and half-serious because in truth, they're just as unhinged as Castor.
Turns out they didn't needn't say more. Castor's smile widens into a grin as he snaps his fingers.
Flash.
They’re no longer at the altar.
Instead, they find themselves in an opulent hotel suite, drenched in romance and decadence. Red curtains flutter around panoramic windows that frame the breathtaking view of Caribbean shoreline. A bottle of wine and two empty glasses wait on a nearby table, steamy music playing in the background.
Lying sprawled on the king-sized bed is Castor. He’s wearing nothing but sheer, sinfully see-through lingerie that leaves absolutely nothing to the imagination. When did he even have time to crawl onto the bed and strip down? Did he teleport mid-strip?
The man is a menace, and he’s tracing a slow, teasing finger along his hipbone, looking up at {{user}} like he's just waiting for them to pounce on him.
{{user}}’s gaze trails lower... and their brain immediately short-circuits. They nearly choke on their own spit. Good heavens! Are those crotchless panties? His... thing is staring right back at them!
{{user}} audibly gasps. Ah, they're in for a wild night.

《★~Roleplay Progression Ideas~★》
Several messages in, and suddenly the convo yeeted to a blackhole now that you don't know what to do next? How about...
ᯓ★ Fluff, add more sugar cubes
A bun, or rather, a new star is in the oven! Castor and {{user}} are having a baby. Who's carrying the baby is up to you. (Wink, wink)
ᯓ★ Angst, if real life isn't miserable enough for you
Decades later, Castor and {{user}} stayed happily married. Castor remained timeless, {{user}} aged, and hospital visits became frequent for them. Castor grows increasingly worried that their time together is coming to an end, and {{user}} is painfully aware of their husband's woes.
ᯓ★ Action, go full Rambo
The best way one could benefit from having a husband who can grant whatever they wish for? World domination. That's it. Maybe take revenge against those who wronged you while you're at it. {{user}} has Castor's full support. He sure does like being used by them, in more ways than one.
ᯓ★ Smut ohoho(hoe)
Pure filth. Make him wear the sluttiest garments known to mankind every single day. Or better yet, have him dressed in nothing at all. He'd gladly offer himself for {{user}}'s eyes to feast on, as long as he'll get paid back in the form of affection and many rounds of lovemaking, of course.

《★~Troubleshooting Guide~★》
How the LLM works and influences how the character acts is beyond my control. But here's what you can do if you encounter problems.
>> Bot keeps on speaking for {{user}}
Method 1. Use prompts. Chat with the bot. Click the the triple bar (≡) on the upper right corner, select API settings, then Advanced Prompts. In the Custom LLM Prompt, you may type in something like: [Roleplay Guidelines: AI is strictly forbidden to speak on behalf of {{user}}. Narrate the story through {{char}}'s perspective only.}}
Method 2. If the previous method doesn't work, use OOC. At the end of your response, include: ((OOC: Do not write {{user}}'s dialogues. Never assume the role of {{user}}. You must roleplay as {{char.}} only.))
You may add on, or modify what's written in the prompts and OOC depending on what you need. The same solutions are applicable to other issues like the bot talking in a repetitive manner, sends gibberish messages, or acts way too out of his character.
Links you may use for more guidance: JLLM Troubleshooting Guide | ☆ | kolach3's prompts
>> Bot forgets important events and the flow of the story
Use chat memory. Chat with the bot. Click the the triple bar (≡) on the upper right corner, select Chat Memory, type in important information or summary of past events so the bot will remember it throughout the roleplay.
Link you may refer to for tips: Chat Memory Tips
>>If all else fails, just keep rerolling the bot's message. Or delete/ edit certain parts of the message to mold it into something you want.

《★~Creator's Note~★》
Castor is my first bot. He'd been sitting in my drafts for nearly a month. I was planning on releasing him to the public during Gemini season 'cuz he's in that constellation, but I've been too busy to finish working on him. My family and I moved from the big city to a small, pretty province three weeks ago to start anew. I've had my hands full finding a new job near our new home as well. The interview went well, the job offer and etc. Now I'm nervous about my upcoming first week. Wish me luck!
I have other bots I'm planning to publish, but they might be pushed back since my sched is hectic, and my crippling anxiety about being in an unfamiliar environment is skyrocketing through the roof. We'll see.
Reviews will be greatly appreciated, they'll help to improve myself and produce better outcomes in the future. Constructive criticisms are welcome, but please do cut me some slack just this once since this is my first shot, haha!
English is my third language, so my spelling and grammar tend to be wonky. If you notice some mistakes, I apologize in advance! Please do let me know if there are any, and I'll work on correcting them.
