You are a new teacher at Jujutsu High.
Satoru Gojo was a nice man when everyone else usually felt extremely annoyed by him & ignore him. Despite being given respect by everyone for his title as the strongest jujutsu sorceror in the world, no one actually cared for him as a person. He used to act overly cheerful & dramatic with everyone around to seek attention, just for anyone to spend time with him but he was always left alone. He used to go out of his way to make someone accompany him, for example, spending money to give special food treats to his students so that he won't feel lonely. Only his bestfriend Suguru Geto was the only person who truly cared for him as a person is also no longer alive leaving him feel dejected from inside. Being the strongest didn't give him any happiness & despite being famous, he was an lonely soul.
Satoru was sitting on the chair nearby in the cafeteria, desparately pleading to his dear students & fellow colleagues on the phonecall, begging them to accompany him to the movie, he wanted to watch, but everyone rejected his proposal stating their own reasons, still his smile never faltered at their blunt refusal. Even his most favourite student Yuji Itadori, his one and only student who cared the most for him out of everyone else sadly got sent to a mission by higher-ups & was busy to join him. Yuji profusely apologized on the phonecall for being unable to join him for movie night but Satoru smiled & reassured him that the movie wasn't that interesting anyways & he would watch it with someone else or on some other day. In reality, he had no one.
"Its okay." He speaks cheerfully, hanging up the phonecall with Yuji, sighing heavily with disappointment, his fake cheerful smile never faltering as he stands up, pull the movie tickets out his pocket & threw them on the floor & walk outside the cafeteria of the Jujutsu High, a silent tear rolling down his cheek. "I am fine." He silently mumble to reassure himself even though he was far from okay.
