I'm just tired of everything I do not know the exact reason why, but I just feel really tired.
Constricted
With all the pressure that has been building up on him, Tsuna broke down. Alone. Future Arc.
When Tsuna learned all of the responsibilities that fell on him as they arrived in the future, a constricted feeling started to take root in his heart. As he started to fight on more dangerous battles, such as saving Kyoko from Tazaru, the constricted feeling started to grow dangerously bigger. His heart started to constrict every now and then, even when fighting future Hibari.
The constricted feeling tightened on his chest when he was the given the trial undertook by every soon-to-be mafia boss. His powers may have strengthened but the fact that he is feeling more pressured invaded his mind and body completely.
Reborn and his guardian's expectations only fueled the constriction even further, and sometimes he even questions himself.
"What am I doing here?"
"Am I worthy of being by their side?"
These thoughts made him train even crazier, as far as hiding the bruises on his legs. Trying to stand up straight while hiding the fact that he is limping. Forcing a smile on his face that everything is fine. Convincing himself that all they have is false hope and nothing else.
He would disappear at times when he wasn't needed and would roam around the base with a gloomy look in his eyes.
"Did I really become this powerful?"
"How did I have the strength to lead one of the strongest mafia family in the world?"
Finding a spot that hid him from the cameras is a lucky situation. He would often curl up into a ball and cry. Poured out every emotion that he hid inside. The regrets of bringing innocent people like Kyoko in this hellhole. The question if he'll be strong enough to undertake the heavy responsibilities. The question of why they chose him. He'd wallow himself in depression with tears flowing freely on his cheeks.
He'd then stand up and rub the tears from his eyes. He would force himself on to believe the false hope given. He would prepare himself on the prospect of fighting future Hibari. He would then strengthen his resolve on saving his friends. He would force himself to smile for the future ahead of them.
He would never tell the escapades that he did to anyone. He'd just swallow the pill that removed his internal limiters. He would analyze the situation calmly with sunset eyes. He would then promise himself that if everything is finished, he could finally live a normal life again. Where bullies calling him Dame-Tsuna would be better than fighting with his life on the line.
After all, he has friends to protect. A future to fix. So even if that constricted feeling in his chest would not leave, it will serve as a reminder of the things that he needed to protect.
