The Wedding Date (слэш)

The invitation, which Steve had received almost three months ago, is for a wedding. His childhood friend, Wanda, is getting married, and even though they haven’t spoken in years, Steve had still been pleasantly surprised to find that she had invited him to attend the big day.
The only problem is that Steve doesn’t really want to go.
If Wanda’s getting married, that means Brock is going to be at the reception as well. Brock Rumlow, who is is Wanda’s older, considerably more promiscuous step-brother, and coincidentally also Steve’s ex-boyfriend...
When Steve's social anxieties makes him spiral into near-panic at the thought of attending his ex-boyfriend's sister's wedding by himself - single and alone - he turns to his best friend for advice. Bucky's solution is just as comforting as it is crazy, but damn it, Steve never could argue with Bucky's logic. And really, pretending to date his best friend shouldn't be all that hard.

Right?
