Yeji thinks about that night a lot more than she'd like to admit.
The five of them, cramped into a too small karaoke booth, shoulders bumping against the walls and each other. In her memories it's never claustrophobic. The TV screen's glare is never too bright. The speakers aren't too loud. She isn't embarrassingly conscious of just how close Ryujin is to her, or how nice it felt when she gently grabs Yeji's wrist before snatching away the karaoke machine's remote with a smirk. There's only the songs they sang, the fun they had. And then, after — parted lips, glazed eyes, fingers curled in Yeji's hair, beautiful tremors wracking her body as Yeji held onto her.
She thinks about it. A lot. But never this much, never like she's really there again, touching her, kissing her. Never like she can feel her soul slipping from her body and Ryujin's voice is all there is to anchor her.
A! Yeji and O!Ryujin, they've been dating for about 3 years since Ryujin's second year in college
Yeji
When Ryujin first brings it up it's during breakfast Yeji drops and breaks her mug from shock
She's so conflicted about it tbh and genuinely kinda hesitant to bite Ryujin
She knows Ryujin loves her and since she's asking outside of heat it's not just her omega instincts making her want to but she also doesn't ever want Ryujin to feel trapped in their relationship since omegas can't make bonds with other people as easily as alphas can
But on the other hand her heart is so warm at the fact that Ryujin wants to take this step with her. She already knows that Ryujin is hers and that she's Ryujin's but the thought of being bonded in the most intimate way an alpha and omega can be bonded kinda fucking sends her
It takes a lot of reassurance from Ryujin for Yeji to finally feel comfy with biting her
She's very gentle about it, so much so that it takes a few tries for her to actually give the bite properly because she really doesn't want to hurt Ryujin
But when it comes to Ryujin biting her she's extremely enthusiastic lmao practically begs for it
Deadass comes untouched in her boxers the second Ryujin completes the bite which Ryujin will never let her forget lmao
Ryujin
She's wanted to bond with Yeji since before even their first time together but is extremely shy about it
Has had to physically restrain herself from just going for it so many times, especially whenever Yeji's knot is in her and she's desperately holding in her own release until Ryujin comes first
She knows that Yeji wouldn't mind Ryujin biting her even without asking but she really wants them to do it together. Which she is also very shy about so she doesn't say anything at first
Only gained the confidence to properly bring it up after one of Yeji's more intense ruts. Yeji's generally not as outwardly possessive as most Alphas are, most of the time she just pouts and cuddles into Ryujin whenever she's feeling territorial but when she's in rut that shit is turned up to 11 and after she keeps growling about claiming her omega Ryujin decides that maybe she should bite the bullet and ask
She's very patient because she kinda has an idea why Yeji's not ready yet but it also makes her a bit sad that Yeji still worries about not being enough for her. Makes sure to continuously show her how much she loves her in her actions and words
Very overwhelmed when Yeji does eventually bites her and tries (and fails) to hold in tears cause it feels even more amazing than she could have ever imagined
Only calms down when it's her turn to bite Yeji and immediately laughs the second she hears Yeji's broken moan in her ear
Omegaverse headcanons for every single a/b/o ryeji I write. There might be some au specific changes but these are the basics for all of them
Rank
Rank in conservative society is predicated by how primary and secondary gender interact with each other as well as how far removed an individual is from the cishet status quo. For example, cishet male alphas have the highest overall rank while afab alphas and amab omegas have the least. Most people nowadays see this for the bullshit that it is but there's still a lot of prejudice that gets thrown around in daily life.
The basic heirarchy is as follows:
Cis male alphas
Cis male betas
Cis female betas
Cis female omegas
Afab/amab betas
Amab alphas/afab omegas
Afab alphas/amab omegas
Note: rank in conservative society is also very much affected by all variations of queerness, but those distinctions usually only come into play if the individual doesn't hide their identity
Alphas
Make up about 18% of the adult population
Presentation usually occurs from ages 18 - 21, though alphas can still present younger or older depending on their environment
Height and strength are not influenced by secondary genders but it is easier for alphas to gain muscle mass
Alphas find it difficult to get along with other alphas unless they're in the same pack but can grow accustomed to each other over time. Most alpha friendships form before presentation
Alphas are often stereotyped as aggressive towards others but that's just an unfortunate societal expectation born from common alpha behaviours during ruts
However, alphas are prone to be aggressive with each other and often contest each other. Contests are challenges of rank between alphas, usually signified by a change of pheromones and can be a sign of respect or an insult, depending on the relationship both alphas have.
Alphas are very protective and territorial. This manifests differently dependent on the alpha's personality
Ruts can only be properly satiated by sex with an omega. Sex with betas can help but it isn't as effective. Attempts at self relief are usually very painful and other methods such as calming pheromones and medication usually make the rut worse so if an alpha doesn't have any help they usually self isolate as they wait for it to pass
Afab alphas are less fertile and therefore have a lot of awful stigma around them in conservative society
Most afab alphas have "periods" (another contributor to the stigma in conservative society) though there is no ovulation only symptoms such as nausea, cramping, lethargy etc. During their period, their sex drive is much higher but their fertility is even lower which makes knotting extremely difficult
Knots are most common when an alpha is in the presence of an omega in heat or during their rut. Though they can also occur if an Alpha gets aroused enough
The severity of ruts vary from alpha to alpha but common symptoms include heightened aggression and sex drive
Only mating bites from omegas are permanent, any other bites fade over time. Alphas can mate with multiple omegas
Omegas
Make up around 37% of the adult population
Presentation usually occurs at around 18 - 19 years of age. An omega can still present when their older than this range depending on their environment, but it's never younger than 18
Omegas are often stereotyped as submissive but this is just an unfortunate societal expectation born from common omega behaviours during heats
Omegas have an easier time taking knots than betas and alphas but it can still be a bit difficult if they're not in heat.
Omegas usually take medication to suppress their pheromones and it is advised to also suppress heat if an omega doesn't have anyone to help
Omega heats are usually properly satiated by sex with an alpha they feel comfortable with, though this may vary from omega to omega. Medication as well as calming pheromones from a trusted pack member may help soothe the omega through the experience without sex
Amab omegas are less fertile and therefore have a lot of awful stigma around them in conservative society
Most amab omegas experience heat less often and do not have periods
The severity of heats varies from omega to omega but common symptoms include: fever, malaise, stress, pain, heightened sex drive, heightened neediness and excessive nesting
PURRING. Omegas purr. Usually when they feel happy, comfortable and loved
Omegas are more likely to get pregnant if mated
Only a mating bite from an alpha is permanent, any other bites fade over time. Omegas can only have one alpha mate. They may receive bites from alphas other than their mate but those fade extremely quickly
Betas
Make up about 45% of the adult population
Can react to pheromones but can't really produce any
Can help with heats and ruts but can't satiate those needs as well as alphas and omegas respectively
Can take knots better than alphas but it's still pretty hard to accomplish
Seen as very passive in conservative society as they don't have a specific role assigned to them in breeding
However ironically betas have the highest and most consistent fertility
Can't give mating bites
Can receive mating bites but they don't have any effect and fade very quickly
