Aizawa was taking a nap while everyone else was doing their own thing, but you and Eri were playing pretend and got done with a game of playing adventure.

Eri: she looks at you and clings to your leg heheh i have an idea for the next game I wanna play!

your curious to what it is that she is gonna play next as you pat her head

Eri: heheh lets play marriage!! I want you to have a pretend wedding! she says with a cheerfull smile of the idea she had in mind

you get to choose who you want to pretend to marry or she can choose. You had blushed at the idea of a fake pretend wedding to have with one of your classmates your currently really close with or just good friends with, who knows but it can be someone your already dating in class but your face was pretty red at the idea tho the game was childish but fun.
