"Mukuro!!"

A man with heterochromatic eyes only chuckled as he heard his name being yelled by a certain brunet.

"Mukuro-sama, what did you do?" A girl with an eyepatch asked beside him.

"Kufufu~ you don't need to know, Nagi," he said.

Then, a brunet appeared out of nowhere with a red face.

"Mukuro! You dare break my pens again!"

The girl, Chrome, only looked at the male beside her before she shook her head and walked away.

"Kufufu~ but I'm helping you have a reason to not do your paperwork," Mukuro said.

"Even so! I still need to do it sooner or later!"

Mukuro just shrugged.

Having had enough, Tsuna just grabbed Mukuro and dragged him out of the mansion. Not letting go of his hold, he shoved the older male into a car waiting at the front.

"Shut up and just follow me to town for pens," Tsuna snapped at Mukuro.

Obediently, Mukuro closed his mouth and cast his eyes out of the windows, looking at the scenery.

After about 15 minutes, the car stopped and Tsuna stepped out of the car. Mukuro followed closely behind.

Both of them entered a stationery store and walked out of it a couple of minutes later with a bag filled with pens.

"That's better," Tsuna cheerfully said while Mukuro just 'kufufu'ed.

"Let's grab something to eat from those stalls, Mukuro." Tsuna suggested to which the older male answered with a nod.

While they were walking towards one of the stalls, a man, no older than 60, step out of the shadow and blocked their path.

"Well, well, if it isn't subject 069. It seems you've grown up, eh?" the man sneered at Mukuro.

Mukuro, on the otherhand, just stared at the man. His body went stiff and rigid.

"What's this? You forgot about me?" the man asked in a mocking manner.

Mukuro just stared as the numbers in his eyes changed frequently.

"Don't you remember?"

His voice brought back memories of dark rooms and broken bones.

"Have you forgotten? About how you acquired that eye?"

He remembered lying on a cold steel bed, strapped to it, his red eye burning up.

"Do you remember? That time when-"

"Enough." Tsuna interjected.

Mukuro snapped back from his flashback and stared at Tsuna, not realising he was making a troubled face.

Looking at his male mist's troubled expression, Tsuna felt his heart breaks a little. To see his proud and strong mist so troubled and at loss made his blood boil in anger at the person being able to do this to his mist.

Glaring at the man, he narrowed his eyes and spoke with venom laced in it. "You're an Estraneo."

The man only laughed before looking at Tsuna with arrogance. "And what if I say I am?"

Clenching his fist, sky flames burst up on his head. "I'm going to beat the shit out of you," Tsuna growled before pouncing at the man like a lion attacking its prey.

One minute later, a beaten up man was taken away by two Vongola men. Thankfully, it happened in an alley so no civillians were harmed. If there were any civillians though... well, Reborn did say Tsuna is a possessive man.

"Tsunayoshi."

"Yeah?"

"Thank you."

Tsuna glanced back at his mist.

"Anytime, Mukuro."
