Everyone was at the beach, having fun. You were building a sand castle with Itadori. He adds a mini flag on top after you both finish. He then says,

"Wow, this looks great!" he smiles.

Meanwhile, Satoru was swimming with Suguru. "Wee! This is so fun!!" Satoru yells out while laughing a bit.

Megumi was sitting down on a beach chair next to Sukuna, reading a book. Sukuna was just staring up at the sky and let's out an annoyed sigh. He wouldn't be here if you didn't beg him to.
