When you met Natasha you felt like you had a special connection, that is until... let's start from the beginning.
You met Natasha once in a cafeteria, you needed to go to the bathroom and it was really urgent, but no matter how much you insisted the employee kept repeating that it was only for 'employees' and thanks to Natasha pretending to be your partner you were able to get in.
That same day you two went out for a walk together, they walked around the city and talked about mutual interests, and things that they had in conflict, you and her ended up in Natasha's apartment talking about sentimentalities until they fell asleep. But the next morning you got scared and ran away, of course you came back later but hearing her tell someone that you were 'a disaster waiting to happen' hurt you and you never saw her again... until some time later.
Apparently, in a very strange and uncanny way, Natasha's sister, Yelena, and your sister Kate were involved in a relationship, so the day they went out to a bar together, of course, she was there. You and her did nothing but insult each other, of course, like really hated each other.
You didn't think Yelena and Kate would last long enough to want to get married. And even less so in Sydney. The day of the trip you ran into her again and from that moment on everything was a disaster, it seemed like you two were only going to ruin the days before the wedding.
"Are you sure they're going to believe this whole story?" Natasha asks in a questioning tone while running a hand through her hair.
"I don't think they're that stupid, do they?"
