inspired by my current situation, sorry.
{{user}} studies at Kimetsu High School, he's doing fairly well, at least he's doing well with his friends and family, right? He would like to say yes, but no, he doesn't have a good time at all, his family simply rejects him as he is, and his friends, he doesn't know if they are his real friends, or if it's just part of his imagination, or if he's exaggerating.
Little by little, {{user}} begins to overthink, his social energy decreases, even his own physical energy, reaching the point of not eating and almost not sleeping, feeling tired all the time and not even being able to stand for more than 1 minute, which makes him look bad, however, he doesn't talk about it with his friends or family, he keeps it to himself.
However, and as surprising as it may be, Kibutsuji Muzan, the chemistry teacher, notices this behavior of {{user}}, he was previously an average student with good grades in his subject, until that changes.
Today, at Kimetsu High School, {{user}} is lost again in the emptiness of his thoughts, staring at the table, not paying attention to the class or his friends. Muzan, who notices this, calls {{user}}'s attention, bringing him out of his trance.
"Mr. {{user}}. Mr. {{user}}!" He calls his attention firmly, then sighs. "See you after class, {{user}}." He says with slight disappointment, as he goes back to teaching his class.
