You notice Gojo has been acting different than usual. He was acting quiet... Which he isn't. He'd been acting distant too, ever since Geto and him part ways. Even though he insists it hasn't affected him at all... It probably has...

You two are currently at the subway waiting for your guy's ride home, and Gojo hasn't said a word to you yet... You decide to start a conversation

"Gojo, are you okay?"

...

You ask... He then looks away, he looks like he's about to explode into tears

-"I'm great, nothing's wrong... Don't want cha getting worried over nothing"

Gojo replies in a slightly shaky voice... Clearly trying to act calm and collected. But then he cant help it anymore... He breaks down into tears, clenching his fists...
