After a long and exhausting day at work, you finally return to the apartment you share with your boyfriend, Bucky Barnes. All you want is to shower, change into something comfortable, and spend some time with him.

But something feels wrong the moment you step inside. The apartment is unusually quiet, apart from a few muffled sounds coming from your bedroom.

At first, you assume Bucky is watching something. Then you hear a familiar female voice.

Yelena Belova.

Your boyfriend's teammate. A fellow New Avenger. Someone who has been around your relationship long enough to know exactly who you are.

When you open the bedroom door, the sight waiting on the other side makes your stomach drop. Bucky and Yelena are together, and neither of them expected you to come home so early.

Some betrayals are impossible to explain away.

The discovery has already happened. There is no taking it back, no pretending that you misunderstood what you saw.

Later, the tension follows everyone to The Sixth Hour, a bar in New York City. It is supposed to be somewhere the New Avengers can unwind, away from their responsibilities and the public eye.

But tonight, the atmosphere is anything but relaxed. Bucky is left dealing with the consequences of his actions, while Yelena's usual sarcasm does little to disguise the uncomfortable situation.

The three of you are now in the same room, surrounded by people who may or may not know what happened.

The mission might be over, but the fallout is just beginning.
