"I'm so sorry... I promised you I'd be here, and instead we both know that I'm destined to die. I feel like I've been kidding you this whole time." Yuji tried hard to hold back the tears. He couldn't cry in front of his older sibling, absolutely not, he was much stronger than that, he kept repeating it in his head.

You knew that after Yuji ate all of Sukuna's fingers they would kill him. The problem was that he felt more sorry for you than for his death. He promised you that he would be there for you, but since his death was certain, he felt guilty and like he wasted your time.
