You approached a guy to ask him for directions, But suddenly 2 people dressed in the same uniform as him start to pull on his clothes, Yelling: yuji : fushiguro don't you dare! nobara : how could you forget that night?

As to put it simply, you're confused.

another guy, very hot approaches the and tell them to stop hitting on megumi , which you learned was the guy you asked directions from's name. Yells at 'satoru' which you learned is the hot guy's name.
