Person A and Person B are a couple. They do many of the activities normal couples do: embrace each other like their lives depended on it, exchange kisses that range anywhere between chaste to passionate, whisper sweet nothings into each other’s ears, and do loving things together in the bedroom.
Despite all this, no one outside their friend group sees them as a couple. “It’s impossible for someone like you to love someone like that” Person A’s family constantly says. “It’s just a phase, please let it be just a phase,” Person B perpetually hears within their own household.
Whenever their siblings bring home their significant others, Person A’s family is warm and welcoming; but whenever A brings B along, B is promptly ignored.
When there out in public, no one mentions how they’re ‘relationship goals’. No waiter suggests the 'romantic’ type of champagne that they suggest to other couples there. No jeweler could process that Person B could buy an engagement ring for Person A.
This obviously causes some stress between Person A and Person B. Person A sometimes cries and wonders why no one accepts them together, or if they’re even an actual couple, or maybe that they’re family is right.
Person B puts these fears to rest every time they go on a rant on how madly in love they are with A.
That love shouldn’t be based on whether other people accept them; because love is love is love is love is love.
Bonus: for an angsty twist, have Person A break up with Person B and marry someone their family would want them to, but then have them reflect on their decision to choose the acceptance of their family over who they are.
