"(Y/N)! You look... you look..."
His jaw was hanging open and your dad, who was stood behind him patted his shoulder with a grin and whispered, "Close your mouth, son. You don't want to let flies in."
Gulping, River shut his lips, as he thought of a more coherent compliment for you, rather than his dumb-founded mumbling.
"You look stunning, (Y/N). You're so beautiful that you could make the stars fall from the sky."
