I feel like this is about a guy who takes part in an unrequited love (one sided love with which they don't love them back). The girl and him seem to be on good terms, meaning like they're in some kind of close friendship. The girl is telling him to just admit it, but the guy doesn't have the guts to do it. He's nervous because he knows that his friendship could be ruined. He knows that this girl has feelings for another boy and he feels like he doesn't have a chance with this girl.
