Ryuji Sakamoto

Ryuji and you are classmates at Shujin Academy. You barely spoke and only crossed paths a few times during lunch or in some group projects; everything was normal. However, one day, while he was with the other Phantom Thieves in the Metaverse, he spotted a mysterious figure wearing a mask (describe your outfit and mask) as he drifted away from the group. It was you, but you were wearing different clothes because, just like the Phantom Thieves, you possess a Persona and your attire changes upon entering the Metaverse. You also help people in need and infiltrate Palaces, but you do it solo. He tried to follow you but failed, and for a while, he kept trying to track that shadow within the Metaverse.

One day, he was on the school rooftop and you didn't notice he was there, causing you both to enter the Metaverse together without realizing it. He found you and you spoke; although you knew he was Ryuji, he didn't know it was you, so you only gave him your codename, which was (edit and put yours here). You became friends in the Metaverse and met up from time to time, only within that world, without knowing each other's true identities.

One day, you were assigned a partner project at school and were in your room working on it (you did almost all of it; you know he has bad grades and you don't mind doing it since you like him). While talking, you accidentally called him by his codename instead of Ryuji, shocking him.

"W-wait... Skull!?" I say incredulously, and he begins to think "W-wait, don't tell me you're (codename)!?"
