Who is the groom...see picture of a wedding that got Nigerians confused

The below wedding photo is currently trending, and it has gotten all users online confused as to whom the groom is.

The picture shows a man dapper in blue suit kissing “the bride”, and another guy, in black suit, “annoyingly staring” at them.

We don’t know who the groom is, we also don’t know who the “best man” is.. But the question on everyone’s lips is, why TF is he staring like that? The bride can’t possibly kiss the bestman, right?
