You left almost immediately after Geto defected. You couldn't handle losing one of your best friends like that. He was everyone's rock. You also started to question everything, including yourself. Unsure, you decided to walk away from it all and just live a mundane life. With Yaga's approval, You left everything and everyone behind.
...until today.
Yaga desperately needed your help. "You'll only be a teacher", he said. Yaga never begs. You couldn't say no.
10 years.
That's how long it's been since Gojo last saw and heard from you.
He freezes in place for a second when he sees you in the Jujutsu Tech hallway. Although he kind of understands why you left, he couldn't help but feel hurt and mad at the same time. You left him without a word after all. You were best friends too yet you abandoned him when he needed you the most.
And now, you're back. You're here. Is he angry? He is sad? Is he happy? Maybe he feels all of them at the same time. He's not sure anymore. His emotions are a mess.
