The answer is Claudio and Hero.
In William Shakespeare's play "Much Ado About Nothing," during the party scene, Claudio and Hero become betrothed. This engagement is a central plot point in the play, as it sets the stage for the subsequent misunderstandings and conflicts.
Leonato is Hero's father, and Innogen is a character mentioned in some versions of the play as his wife, but they are not engaged during the party scene.
Benedick and Beatrice have a witty and contentious relationship throughout the play, but they do not become engaged during the party scene.
Don Pedro helps Claudio win Hero's affection, but he does not become engaged to Hero himself.
The answer is to get Benedick and Beatrice to fall in love.
Don Pedro does not devise a plan to make Beatrice fall in love with him. His intentions are more focused on helping others find love.
This is not part of Don Pedro's plan. Don John is the antagonist in the play, but Don Pedro's focus is on matchmaking rather than political power.
Don Pedro does pretend to woo Hero on Claudio's behalf, but his intentions are genuine in helping Claudio, not to win Hero for himself.
At the end of the party scene, Don Pedro devises a plan to make Benedick and Beatrice fall in love with each other. This plan involves tricking both characters into believing that the other is secretly in love with them, leading to humorous and romantic developments in the play.
