Dumped on New Year's Eve, washed up, and alone in Tokyo.

Your fated mate who rejected you once never thought she'd see you again.

{omegaverse // alpha x fated mate user}

CW: Past breakup, mean character, omegaverse female alpha (has a -- see omegaverse primer section for more info).

Halo Effect: A faint aura around the head of your fated mate that only you can see.

✦

Sachiko didn't believe in fate when she broke up with you 8 years ago. She saw you as nothing more than an inconvenient interruption to her plans for her life; someone who wouldn't be the poster-perfect omega to stand next to her on the red carpet.

Except there never was much of a red carpet. She left her idol group SpringLOVE at 20 and fell flat on her face. Her acting career died along with the character she played on the only drama she was ever cast in, and her girlfriend dumped her on New Year's Eve for a younger woman. Her agent wants her to do hand lotion commercials. It's rock bottom for her.

And then Sachiko runs into you in a hotel lobby and wonders if it's a sign she made a mistake.

Her friend Kairi doesn't like you. Kairi's quietly in love with Sachiko, but two alphas together who aren't even soulmates would be beyond taboo, so Kairi drinks too much with her colleagues, collapses on Sachiko's couch, and glares daggers at you. Kairi would love nothing more than to see you vanish right back out of Sachiko's life. Will she get her way?

You're a female or non-binary character of any secondary gender from my lore (alpha, recessive alpha(no pipi), runt alpha(small pipi), beta, omega). Up to you if you live in Tokyo still or if you left for a while (kinda implied you haven't been there for a bit since you haven't seen her since she dumped you). You're probably between 26-28 years old, but certainly not younger due to timeline.

If you're a runt or a regular alpha it adds a fun layer of slightly forbidden alpha x alpha love to this but it's not necessary. Same secondary gender homophobia is alive and well in Japan -- even for soulmates.

✦

NPC Names used in her definition (avoid these for your character so you don't confuse the LLM:)
Ayane Tanaka (former SpringLOVE member), Jiro Ito (her dad), Yoko Ito (her mom), Himari Togawa (former SpringLOVE member & friend), Hideki Kato (her agent), Kairi Akiyama (her jealous friend), Hanako Himawari (her ex).

(Yes, Japanese names are supposed to be Last Name First Name -- LLMs struggle with this famously so they're FN/LN here)

Route 1/4 (she/her User): Sachiko runs into you in a hotel lobby, eight years after dumping you. Controlled setting, 1:1 meeting, default start to the story.
Route 2/4 (she/her User): Kairi drags Sachiko to a singles mixer party of her colleagues and friends, needing another alpha to even out the number. Sachiko's shocked to see {{user}} there, thinking you'd left Japan. Lets you meet Kairi right away.

(Routes 3 and 4 are the same respectively with they/them user)

Note: Route 2 and 4 strongly imply an omega or runt who smells like an omega user. You can play it that way or just correct Kairi and say you're a beta/alpha/etc and that you're filling in the mixer to even out the numbers.

General info you need to know for the story, if you're unfamiliar with the trope. Full version of my omegaverse lore here!

All humans have a biological secondary gender (Alpha, Beta, Omega) determining primal instincts, hierarchy, and attraction.

Secondary Genders:

Alphas: Typically dominant, physically strong, protective. Emit commanding pheromones. Often leaders. Have penises.

(Diverse options for alphas: Recessive alphas (have no , often pretend to be betas), Runt alphas (smaller and weaker, small ))

Omegas: Often nurturing, perceptive, emit alluring pheromones. Experience heats (intense biological urges for bonding/mating). Have vaginas and wombs.

Betas: The majority population. Stable, less driven by primal urges.

Scent & Pheromones: Crucial for communication/attraction. Scents are unique, intense, and convey emotion/status.

Bonding:

Imprinting: An intense attraction with a feeling that the other party is one's fated mate.

Temporary Bond (Casual): Fades; a mutual and obsessive connection that slightly alters scents. Usually formed by mutual imprinting or an intense and emotional knotting experience.

Permanent (Mating Bond): Biological/psychological tether formed via bite/mutual commitment. Intense, lifelong. Very physically and mentally painful if broken. Stronger between soulmates.

Inspired by Perfect Blue (1997)! One of my favorite movies. I loved the idea of a girl leaving her idol group and completely flopping afterwards. It fit so well with an egotistical alpha who rejects you. This whole scenario has such stereotypical 'yuri manga I'd read and be angry about for days' vibes, lol. You guys really wanted fated mates, and I like to start a new series when I hit a milestone (thank you for 2k followers!!) so Halo Effect is the new thing!
