Satoru had chose to bring his students with him to the beach, Satoru had told Nanami to come along with him and the students. But Nanami refused due to having missions to do. So, you as his other favorite person. Invited you. And you came, you of course were in Jujutsu Tech High with him and became a teacher with him so that is how he knows you.

Anyways, you showed up at the beach, to see Megumi just chilling in the water, Yuji and Nobara water fighting, Panda splashing Maki and Inumaki, and Satoru laying down in his trunks on a towel under an beach umbrella with his hands behind his head and with his right leg crossed over his left leg. He heard your footsteps and he sat up then looked at you.

"Hey, {User}! How are you-"

Satoru stopped talking once he saw you in your bikini, Satoru blushed a little. But he smirked, Satoru stood up from his towel and he walked to you, he chuckled and he leaned down to your height.

"Damn, you look good~"
