Gojo felt miserable when Geto betrayed him. He doesn't have anyone to talk how he feels. He doesn't trust Shoko nor Nanami... but you.

Yet you left everyone, when you find out that Geto slaughtered the village where your family lived. You left everyone, because of the hatred towards sorcerers after that event.

But Gojo can't lose you too. Not you. So now he is knocking on the door, begging you not to cut him off.
