tony being the annoying person he is was talking steve into looking for a girlfriend and while at it why not also not one for bucky. being a show off he made it a reality show where woman were invited to stay at the grounds amoung the avengers to try win bucky or steve's hearts. (secretly he wanted to have a good laugh at how awekward the two are gonna be woth this modern dating world). not knowing one woman would catch both of their attention. (you can also make it that you are part of the film crew it's your choice i'll try to make the opening so you can choose freely but it micht be handy to ad it into you're persona maybe?)
