Ten Years of Guard — A Palace Bodyguard Otome Roleplay (Forbidden Vow Slow Burn)
Final Product: Ten Years of Guard
Cover
The 16:9 key art: Kaelen Ashford at the edge of the candlelit palace corridor, one hand on his sword and the silver locket at his breast, the throne room burning gold far behind him and the night city beyond the arched windows. Painted in the world's own refined semi-realistic painterly direction.
Gameplay
Actual gameplay: the route opens in an empty corridor at night. Kaelen's portrait holds the left panel while the narration sets out the ten years of silence, Lord Caelum's questions, the locket on the floor and the execution order dated three days before the rebellion. Continue and the free-text composer wait below.
Gameplay
Actual gameplay with the controls hidden for a clean read: the same opening turn, Kaelen's one true sentence — "I need you to know it before he tells you. Not after. Please." — and the locket scene laid out end to end. The interface is the conversation, not a menu.
Gameplay
Actual gameplay with the premise expanded: the full hook in view above the opening turn — the guard who has loved you for a decade, the vow in your mother's handwriting, and the sealed record that could clear his father's name or destroy them both.
Ten Years of Guard is a playable palace bodyguard otome roleplay — a forbidden-vow slow burn about the man who has stood between you and every blade for a decade, and the locket that proves he was never allowed to love you. Directed live by AI and running in your browser with nothing to install.
You are the Empress. Kaelen Ashford is the guard who has shadowed you for ten years: a wall, an order given twice, a man who speaks with actions and never asks for anything. Tonight he stops you in an empty corridor to warn you that Lord Caelum has been asking about his family. Later, during a scuffle at the outer gate, the locket slips from beneath his armour — your mother's portrait on one side, and on the other, in her handwriting, a vow that he would guard her child's life and never claim her heart.
What follows is not a confession scene. It is an investigation into three silences: what really happened in the rebellion that killed your parents, what the locket has meant to him for ten years, and why Lord Caelum is quietly building a case against the one man you trust. Compare the official chronicle to the palace's private records. Ask the seamstress what she saw. Decide whether to open the locket with him — or let him keep the only thing he has ever allowed himself to want. Play Ten Years of Guard →
Game Features
- Live LLM Narrative Direction — nothing here is a fixed script. A deepseek-v4-flash agent reads the action you type, keeps Kaelen in the register of a man who says one true sentence and then goes still, and writes the next beat, the subtext and the silence after it as you play. The same agent planned the premise, the default opening in the corridor, three investigable threads and four locations from a single world prompt.
- A Guard Who Loves You in the Gaps — Kaelen does not explain himself in paragraphs. He says one true thing and then stops: "My lady, Lord Caelum has been asking about my family. If he comes to you with what he finds — I need you to know it before he tells you. Not after. Please." Lord Caelum is too courteous to be harmless. The narration never tells you what you feel; it tells you what his hands do.
- Answer In Your Own Words — the free-text action box is the whole interface. Wait for him to finish. Ask what the locket holds. Order him to open it. Say nothing and let the silence do the work. Every typed beat lands differently, and the story remembers which silences you chose to break and which you let stand.
- Three Investigable Threads — What really happened in the rebellion? (the main thread: a chronicle written by Lord Caelum's grandfather, a rebel leader captured alive and executed within a day, your mother's guard dismissed the week before the attack), What is in the locket Kaelen never opens? (a clasp worn smooth from touching, a seamstress who once saw him weep, a portrait and a vow in your mother's hand), and Why is Lord Caelum investigating Kaelen? (execution records requested, an agent near the old barracks, officers who despise the guard's influence). Each carries clues, actions, discoveries, a reveal and consequences that change the ending.
- A Vow That Was Never Meant to Be a Chain — your mother spared Kaelen on the pyre's edge and told him the vow was his to keep or break. Ten years later he still does not know whether keeping it honours her or betrays you. Reveal the Caelum conspiracy and his name is cleared; open the locket with him and the vow becomes a choice; let Caelum move first and the last witness is silenced; protect his secret and the trust deepens while the Caelums keep their grip. Refusal, confession and forgiveness are written as real outcomes, not failure states.
- Two Cut-Out Sprites, Four Painted Scenes, Zero Install — Kaelen's silver-and-black standees were cut out with birefnet-general into true transparent PNGs, so he stands cleanly over four painted settings — the candlelit palace corridor, his own quarters, the rebellion archive and Lord Caelum's estate. The whole story is a mobile-first page: free to start, nothing to download.

Kaelen in close bust — the scarred hand, the unopened locket, the level grey eyes of a man who has already decided to die for you and is only now deciding whether to tell you why. Cut out from the route's 3:4 key art with BiRefNet into a true transparent PNG.
Production Process Breakdown
Stage 1: World Buildingdeepseek-v4-flash
The world "Handsome Men in the Galaxy" set the house art direction — refined semi-realistic painterly, value-defined contours, organized shadow planes, warm translucent midtones, small controlled speculars, idol semi-3D painterly. For this route the AI narrowed it into a palace register: candle amber, midnight indigo, silver-black armour and cold marble, with the hush of a corridor after the court has gone to bed.

Stage 2: Roleplay & Story Draftingdeepseek-v4-flash
From the one-line premise — the guard who has loved you for ten years under a vow never to claim your heart — the agent wrote the playable spine: a five-link relationship graph, three investigable threads with clues and consequences, four locations, four story directions and the default opening on the night the locket falls.

Stage 3: Key Art & Cast Portraitsgpt-image-2.5-sunburst
The 16:9 key art was painted with GPT Image 2.5 Sunburst as a single staged scene — Kaelen at the edge of the corridor, the locket at his breast, the throne room burning gold behind him — so the cover is literally the first image of the route. The official 3:4 key art was reframed from the world's own Kaelen card, preserving the same face, armour and candlelight.

Stage 4: Scene Paintinggpt-image-2.5-sunburst
Four 16:9 backgrounds were painted at 1536×864 to stage the investigation: the candlelit palace corridor, the guard's quarters with the open locket on the table, the rebellion archive under its green lamp, and Lord Caelum's estate study with the family portrait turned to the wall. Each keeps the lower third calm and uncluttered so dialogue and sprites can sit over it without fighting the art.

Stage 5: Transparent Cut-Outbirefnet-general
Both Kaelen standees were background-removed with BiRefNet into true transparent PNGs, so he composites cleanly over any painted scene — no grey box, no matte edge — and can be swapped mid-scene without re-lighting the background.

Scene Backgrounds
BG
The palace corridor at night: a long candlelit gallery of tall arched windows, crimson banners, silver sconces and a polished marble floor carrying the flames, with the throne room glowing at the far end. This is where Kaelen stops you with no one in earshot — the geography of the whole route: a man and an Empress, ten years of silence, and a corridor that keeps neither of them safe.
BG
The guard's quarters: a narrow bed, a stand holding his silver-and-black armour, a sword against the wall, one candle, a sealed letter — and the locket lying open on the table, your mother's portrait catching the light. This is where the vow is kept, and where the second vow has slowly become his whole life.
BG
The rebellion archive: towering shelves of leather ledgers, sealed scrolls, iron filing cabinets and a long oak table under a green-shaded lamp, dust hanging in the lamplight. This is where the official lie and the buried truth are both filed — and where the chronicle written by Lord Caelum's grandfather can be compared to the palace's private records.
BG
Lord Caelum's estate study: dark wood panelling, a massive desk stacked with ledgers, a marble fireplace, heavy velvet curtains and a family portrait turned to the wall. Opulent, orderly and dangerous — the room where the conspiracy's second generation keeps its ledgers and quietly erases the rebellion's true history.
