Tsuna knew from childhood that one day he would become the heir to the Vongola like everyone else. Therefore, Primo trained him from the age of six. Now fourteen-year-old Sawada fought with his father at the next training session. For eight years, the boy learned a lot from his adoptive father, he inherited the will of Primo and not only him.

It was now the middle of summer, the day was very hot, sweat dripping down Tsuna's forehead when he tried to touch his father, it was his test of control of the flame and the fourth attempt. Unlike Sawada, Giotto looked cheerful, although he was also pretty tired. His boy became much stronger than before and training was no longer so easy.

"Maybe you want to take a break?" asked the older man, he himself wanted to rest.

"No, this is the last attempt," Tsu's words made Giotto proud, he always admired his tenacity.

"Okay, last try for today," the boy nodded in agreement and took the first step. He sharply pounced on the blond and tried to hook him with his flame, but the man dodged safely, though he did not notice that the boy managed to drive him into a trap and almost touched him. Giotto managed to grab his hand and throw it over himself, Tsu landed on his shoulder blades with a quiet moan, but a victorious smile spread on his face, a posthumous will burned on the sleeve of his jacket, and a piece of black fabric from the same jacket remained in the boy's hands.

"Hurray, I did it, I finally passed your test."

"Great job, you did a good job, mio tesoro *," a displeased sigh was heard from the boy, Primo helped him up, "you almost defeated me, someday you will become stronger than me," the man gently ruffled his son's hair after helping him to get to his feet, it was barely noticeable, but in the eyes of the blonde one could see sadness, it seemed that Primo was about to cry. Tsuna noticed this, but did not attach much importance to it, his father was prone to drama.

"Dad, stop, I am no longer a child and I have asked you a million times not to call me that, I am too grown up," complained Tsu, dodging his father's tender hand.

"I'm sorry, I'm sorry, but no matter how old you are and where you are, you will always be mio tesoro *," Giotto did not listen to Sawada's protests and gently kissed him on the forehead, straightening the unruly hair of the brown-haired woman.

"Dad!" the boy was indignant and pouted his lips, to which Primo only laughed and hugged his son tightly, Tsuna floundered for a while, trying to escape from his father's arms, but ultimately gave up and just relaxed, and allowed the blonde to pull him into his arms, so they stood , for a while, until Sawada finally broke free, "That's it, dad, that's enough of this embarrassing."

"How about a snack?" asked the blond, pushing his son towards the small summer terrace. There was already a plate with several sandwiches and a jug of lemonade.

"I made sure you don't go hungry after a strenuous workout, mio tesoro *," Primo sat Tsu down at the table and flopped down beside him.

"Thank you, dad," Sawada smiled, dad always knew what he would need after training or his favorite drink, he always knew everything.

"You are always welcome, mio tesoro *," the man gently ruffled the child's hair again, Tsu just snorted in displeasure, but otherwise remained silent.

"Dad, I've always wondered why you call me mio tesoro *?" asked the brown-haired man, carefully studying Decimo's face.

"It happened when you were still very young. I saw you for the first time and you seemed so small and fragile that I was afraid to even touch you, it seemed to me that you would crumble as soon as I took the wrong step, and when I finally gathered my strength and still took you in my arms and you didn't just cry. You smiled so broadly and sincerely that a thought immediately flashed through my head. "My treasure, you are my little treasure," a sentimental smile appeared on the man's face, and the sadness disappeared for a while, it was obvious that he plunged into old memories in those days when Tsu did not even know how to walk and speak properly, and that was very for a long time, so long ago that the boy himself does not remember. His father's words made him blush, embarrassed and fix his gaze on the glass of lemonade. The cold drink helped to cool down well in the heat and get rid of thirst after a long workout under the pouring rays of the summer sun. At that moment when the child took another sip, an unexpected stream of childhood memories washed over him too. When the first Vongola first made homemade lemonade according to a special family recipe that his mother taught him, although the boy had never seen his father's parents or any other blood relatives, at that moment when a sour sweet taste spread over his tongue, he felt the boundless love of his grandmother and grandfathers, as if they were standing next to him, and his dad to him, it was a strange feeling, as if he knew for sure that this was so and not one force in the world could convince him of this.

When Sawada told Primo about this, he smiled gently at him and explained that perhaps he had experienced hyper-intuition for the first time, albeit in a rather strange way. On that day, the child asked the blond man for a long time about his pedigree. But these are things of bygone days.

After the snack, the training continued for several more hours, then Tsu had a lot of free time until the evening, most of the day he spent surrounded by friends who also passed the exam for the level of posthumous will and now they could spend some time together until it was time to go to bed. Before going to bed, for some reason, he was drawn to read an old children's book, which he loved so much when he was little, his father often read to him at night. Today he had insomnia due to intuition, so he tried to somehow distract from it.

Suddenly there was a knock on the door, Sawada wearily muttered an invitation to enter, and his father's blond hair appeared in the doorway.

"I came to wish you good night," the man sat down on the bed next to his son, it was noticeable that he was hiding something in his hands behind his back.

"What have you got?" The brown-haired man asked, trying to look behind the older man's back and see the object.

"I found something." When Primo handed the object to the boy, he stared at him in shock. It was an old battered lion toy with a collar with the inscription "Natsu" around its neck.

"Where did you find him?" the boy was surprised, he thought that the toy had disappeared several months ago.

"In the attic, it looks like one of the maids threw him there," explained the first Vongola, laying the toy next to his son's head.

"Thank you, of course, but I'm already too old to sleep with a plush toy," Tsu really believed that he no longer needed Natsu, because he had already grown, but some strange feeling, which he resisted, tried to make him hug the lion cub and burrow my nose into his faded fur. This calmed and reminded him that everything would be fine, even when his intuition was loudly warning about something, only the boy still could not understand what.

"Then I can pick it up?" the blond pulled his hand to take the toy before he could do it Tsuna stopped him.

"Not!" the boy screamed so unexpectedly and sharply that he frightened himself. He blushed and turned away from his dad when he realized that he was acting like a child.

"So you still want him to stay?" Primo smiled and bent down again to kiss his son gently on the forehead. The child did not answer, just nodded, still looking at the wall, "Do you have insomnia?" again hesitant nod, "Then I know a good way to fall asleep."

Suddenly strong hands lifted him from the bed, instinctively Sawada wrapped his legs around his waist, and his arms around his father's neck. His shock lasted a few seconds before he tried to break free.

"Hey, stop, I can drop you," after a moment the boy stopped turning and looked displeased at the blond, "Don't pout, I want to help."

With these words, they set off in their own way along the winding corridor. Tsuna knew this road well, so he was not surprised when they found themselves in front of a large oak door and went inside. Father's study has not changed at all, it is still cozy and quiet. As a child, the boy thought that he was in another world when he came here. The older man sat down on a black leather sofa, already shabby from time to time, and sat the heir on his lap. From somewhere in his hands, a book was swearing, which Sawada had read a few minutes ago, he must have taken it with him, along with a plush lion.

"Do you remember when you were little and could not sleep, you came here and asked me to read to you?" Tsu wanted to object and say that he was too old for such gatherings on his dad's lap, but in a moment the desire disappeared, it was too comfortable, sitting like this, snuggling with his father, inhaling the smell of old books mixed with expensive men's cologne, feeling like a gentle hand the blonde strokes his son's disheveled hair and listens to the velvet voice of the blonde reading his favorite book. Just like in childhood, when Tsu was so small that he could completely fit on his father's lap.

His gaze slid to the opposite wall and caught on a small corner of the office. There were several drawings that the boy drew at different intervals. Giotto was always so proud of them, as if Sawada was a famous artist and hung him in the most prominent place to admire them, at least he himself always said so when Tsuna asked him. There were also several framed photographs hanging there, on one were all the keepers and Elena, on the other the keepers were sitting with the children in the garden and looked very happy, and the third was taken not long ago in the garden, but ten years later. Two more were made in the same vein, only they depicted a four-year-old Sawada in the arms of Giotto and tightly hugging Natsu, and in the second, a fourteen-year-old boy was sitting on a luxurious chair, and a blond man stood behind and held his hand on his son's shoulder. Primo loved these photos so much that he had a copy, one under the cover of the watch along with all the Vongola keepers, and the other where the little brown-haired man sat on his lap, he always carried a cloak in his breast pocket so as not to lose.

Already when the eyes of the future boss Vongola began to close, he felt his father's lips touch his forehead.

"Ti amo, mio tesoro *. Never forget me, okay mio tesoro *? Please forgive me. I love you so much and I will always love you, remember this." Before the boy had time to say something to Giotto, he squeezed him in a tight embrace for the last time and Tsuna felt his father's flame touch his forehead. First, a frost ran over his skin, and then warmth spread inside his body, his arms and legs poured with lead, and his eyelids were so heavy that they could not be opened. Suddenly, a terrible fatigue accumulated on the future boss of the Vongola, which was impossible to fight, and after another moment the boy completely plunged into darkness.

"I love you, my treasure. I love more than life."

Notes:

Мio tesoro is my treasure.

Ti amo - I love you.
