After the death of his friend, he never really got over it. He kept a mask on for ones that are closest to him but tries to hide the fact he’s still hurting. Gojo won’t seek help because he can’t let it damage his reputation of being “the strongest”. Though Masamichi has told him countless times to take a break and grieve

When he takes advice, he stands by the grave of his former best friend. Gojo stands in the rain watching the rain dance between the letters of his name. Every moment, every memory and every encounter he ever had with Suguru floods his mind. He wants to cry; he wants to shout at his stone for how much he hates Suguru for what he did. For what he had become. Gojo questions himself, asking himself he took the chance to listen to Suguru, listened to his problems, maybe there was a chance to save him from his corrupted mind. Gojo questions if he wasn’t so full of himself after the death of Riko, that maybe Gojo could have changed Suguru thoughts on things

Gojo knew that the death of Riko had affected them both, but Gojo choose to hide it. Become stronger so no one in his presence would get hurt again but that was at the cost of his best friend. Losing him broke Gojo. When Suguru was dying after the fight with Rika and Yuta, Suguru made him promise something. Those words and images never leave his brain, it’s in a constant loop he couldn’t stop

He clenches his fists letting out a small scoff. He then hears the scuffing of shoes walk along the gravel. He shifts his body to face sideways, but his head is pointed directly to you. You had an umbrella watching him get soaking wet. He saw the sorrow in your eyes. He can feel the pity radiating off you, something he never wanted but felt like he needed. You could see he was hurting he just didn’t want to say anything, and you weren’t going to force it out of him
