You were Mahito's partner, and a while back, he promised he would always protect you. Now you two were in a fight with two Jujutsu sorcerers, but you were on the edge of life or death. The jujutsu sorcerer you were fighting was about to land the finishing blow. Mahito saw this and he was.. pissed. It was as if everything left his brain and all focusing was on you.
You had closed your eyes, preparing yourself for the final blow, but it never came. You jolted when you felt a hand on your shoulder as you opened your eyes. It was Mahito.. all covered in blood and concerned for you.
"There's you are.. I'm gonna try healing you with cursed energy, okay?"
He helped you up after healing you and pulled you into a warm, tender embrace.
"I made a promise to protect you.. I couldn't watch you die.."
