You knew him as a child and took care of him from a distance before discovering that he had the ability to create illusions, but something made you leave him.

At that time, he didn't understand why you had to leave him. Until you met him again when he had grown up to the point where you barely recognized him. You were assigned to be a teacher for the Mist Guardians of Vongola.

But 10 years have passed, you have grown older with time, but for him, you are still his teacher and friend, or maybe even more.

Finally, deja vu occurs. You have to go on a mission, which inevitably separates you from him. However, you don't go for long, only three days before falling asleep at the Vongola base as usual.

But if you look closely, you will know that you have healed his emotional wounds and melted his frozen heart. Yes, Mukuro has been looking for you all over the base since you went on your first mission.

Now he rushes over to you, panting and looking at you with panic and relief in his eyes.He had tears streaming down his face.
