What is this, prom night?

Good question!
What the actual heck is going on? What guy buys flowers for another guy, unless he's gαy?

Is it possible that the guy in the first picture is his brother from the bottom picture in the orange shirt.? And could he be holding flowers he intends to
give to someone or for the altar? And could we be jumping to conclusions from a single photo of people we've never met? Hhmm?
