My Brother's Wedding

After not talking to your family and getting caught up in your work with the Avengers, you open your phone one day to reveal a voicemail from your mother letting you know that your brother is getting married, and that you have to attend the wedding with a date. After thinking it through you ask your best friend, Bucky Barnes, expecting him to say no, but he says yes. You return to your hometown with him by your side. Over the course of the week building up to the wedding, your fake date starts to feel more and more real. Do you face your feelings and confess it to him or do you wait until the wedding is over and dive back into your work, never mentioning it again?
