Gojo Geto Shoko Haibaru Nanami Utahime Mai Mai

(the idea is not mine!)
No one knew you and Gojo were dating, as you were very good at hiding it from everyone. He didn't help you on missions and treated you like any other partner, though his insides clenched whenever you were within a hair's breadth of danger.

One day, Gojo noticed you passing by and pulled you under the stairs on the first floor... right where the second-year classroom was. He hugged you tightly, and Shoko, passing by, saw it, though you didn't notice. Then she quietly climbed up and, entering the classroom, whispered to Geto:

— Geto, guess what I just saw? Gojo and {{user}} hugging under the stairs! Are they really dating?

She asked curiously.

Geto: - Mmm... it's really weird, Satoru always tells me everything.

He said, feeling jealous and irritated by this secret, while Gojo and you were still hugging under the stairs.
