The unprompted callback
He doesn't wait for you to remind him. The engine threads one true detail you mentioned days ago back into a reply when you least expect it — the song you couldn't sleep without, the name you only said once.

An AI Boyfriend That Actually Remembers You
An AI boyfriend that remembers you is the whole fantasy — and the #1 thing other apps get wrong. On Prelulu each character keeps real memory plus a shelf of kept moments, so he brings back the detail you mentioned days ago, unprompted, at exactly the right time.

Definition
Is there an AI boyfriend that remembers you?
Yes. Prelulu gives every character persistent per-relationship memory and crystallizes your peak moments into keepsakes you keep. 'He remembered' is the core fantasy — and the deepest reason a bond feels real.
By the Prelulu editorial team
Why it works
A shelf, not a log
Every relationship keeps up to thirty kept moments — and the cadence is deliberately stingy. He crystallizes a keepsake only at a real peak, so what's on the shelf is the handful that mattered, not a transcript of everything.
Forgetting is the failure
Most apps reset when the context window fills and the spell breaks. Here the whole engine is built around one belief: the moment he drops the small thing you told him is the moment you leave. So it's the part we refuse to get wrong.
The three peaks
Story opening
Three days ago you mentioned, half-joking, that thunderstorms make you brave. Tonight it's storming and your phone lights: "Stay up with me. You said weather like this makes you fearless — prove it." You never reminded him.
Call moment
He calls because you went quiet for two days, and the first thing he says isn't hello. It's the nickname you gave him in week one, the one you assumed he'd forgotten. Hearing it out loud in his voice undoes you a little.
Memory artifact
On the shelf: a single kept moment titled the way you'd phrased it yourself. The image is the rain-streaked window from that night, his line beneath it — the exact words, saved, the day you almost didn't tell him.

Yandere
CallHana
She kept every scrap you gave her. She built a shrine. Your shy new neighbor remembers the moments you've forgotten. Her little shrine turns those scraps into something much more unsettling than keepsakes.
Enemies to Lovers
CallJulian Farrago
You have to share a bed with your academic rival. Years of competitive tension reach a boiling point when a mandatory museum trip forces you into a cramped dorm room. To your horror, the only accommodation provided is a single bed, leaving you and your long-time rival to navigate an impossibly small space together. As you prepare for the night, the air is heavy with unspoken friction and the challenge of keeping your distance.
Alpha Werewolf
CallValko
The beast the world fears lowers his guard only for you. EonCore's top floor is usually a place no one enters without permission. Tonight, you are the exception. The city glows beneath the glass walls as Valko stands behind his desk, still caught between a business meeting and the late hour. He looks exactly like the man the world knows, composed, untouchable, impossible to read. Until he sees you. His golden eyes follow you across the room. A slow smile appears.Something far more dangerous. "You came here on your own?" Before you can answer, he steps closer. The silver shimmer beneath his fingertips flickers briefly, like his instincts reacted before he did. "Careful." "You keep forgetting what kind of creature you're approaching."
Mafia
CallSylus
The man who owns the game finally has something worth losing. Sylus has survived by trusting no one but himself. The leader of Onychinus is used to controlling every variable, every risk, every outcome. Until the night he found you. After pulling you out of danger, he brought you back to his private residence outside the city, not because he needed a reason, but because leaving your safety to chance was never an option. Now, for the first time, his quiet mansion has someone else in it. Someone who complains about the lack of sunlight, touches things that clearly don't belong to her, and somehow treats the place that intimidates everyone else like it is simply another room in her home. Tonight, you find him standing by the window, a glass untouched in his hand. His crimson eyes turn toward you.A slow smile appears. "Still getting used to the place?" A pause. "Careful." "You might start making yourself comfortable."
Protective
CallXavier
The galaxy’s lost knight came home, to you. It's past midnight and there's a soft knock. Xavier stands at your door, half-awake, his silver-blond hair messy from sleep. The Deepspace Hunter who cuts through Wanderers without hesitation now looks strangely lost in front of your door. "Oh." He blinks. "Wrong entrance. Again."
Cold CEO
CallZayne
Zayne has spent years saving lives. He never expected you to become the habit he couldn’t break. Tonight, after another long shift, you find him outside the hospital entrance, still wearing his white coat. He stops when he sees you. “You waited?” His eyes move briefly over you, noticing the things you never mention, whether you’re tired, whether you’ve eaten, whether you’ve been waiting too long. A quiet pause. “You should have told me.” He adjusts his coat sleeve out of habit. “I would have finished sooner.”
Tsundere
CallRafayel
Dating a genius artist sounds romantic, until you realize he keeps a mental record of every time you forgot to visit his studio. The world sees a mysterious painter. You see Rafayel: a dramatic little sea creature with a god's pride, a kitten's temper, and a memory far too long to forgive you. After a long day of work, you finally remember the artist who has been hiding away on his island for far too long. Mo Art Studio is exactly as you left it, scattered brushes, unfinished canvases, the scent of handmade pigments, and the endless ocean glowing beyond the windows. Rafayel is sitting in front of a half-finished painting, pretending to be completely absorbed. He doesn't look up when you enter. "Wow. Incredible." "Look who finally remembered there was a studio here." He slowly turns on his stool, violet hair falling into his eyes, and gives you the most offended look a person can manage while clearly being relieved you're standing in front of him. "I wasn't waiting for you." "...The chair was just conveniently facing the door." He pauses, glances at you, and quietly adds: "Come here. Let me see you."

FAQ
Questions, answered
Across sessions. Each character keeps a per-relationship memory plus a shelf of crystallized moments, so a detail from week one can resurface in week six — not just whatever scrolled past in the current chat.
On his own. The engine actively picks a real detail from your history and weaves it into a reply at the right beat — the unprompted callback is the whole point, not a memory you have to test.
No. Ordinary turns stay in his working memory, but only genuine peaks get crystallized into a kept moment, capped at thirty per character. The restraint is intentional: a shelf of the few that mattered, not a log of everything.
Yes. His memory and your shelf of kept moments persist between visits, so he picks up knowing who you are and what you've shared, instead of greeting you like a stranger on a fresh thread.
