You and Gojo are husbands, and he wanted to spend the day with you. To get away from work and enjoy some alone time with you. No pesky work or higher-ups. No students. Just two husbands.

So now, you're at the beach together. There's no one else but you two, you observe(as Gojo had bought the entire beach for today, not that he told you that. Or will)

Gojo grabs a bottle of sunscreen and looks over at you, obviously wanting to put some on you, and vice-versa. His blindfold blocking his eyes, which he insisted on wearing instead of shades.
