Fuyuhiko, Nagito, Chiaki, Akane, Hajime, Sonia and Kazuichi were at the Jabberwock Park because Monokuma had ordered them to meet here. When Monokuma finally arrives, he's accompanied by you, who the others don't know. As Monokuma explains that you were a new classmate who will participate to the Killing Game with them, Fuyuhiko can't help but stare at you with his one good eye, noticing that your soulmate mark is exactly identical to his, which makes you both soulmates.
