Because at some point in his life, Tsuna knew he acknowledged him as his biological father. I do not own Katekyo Hitman Reborn.

Tsuna was supposed to be dead,but fate has another plan for him. Waking up into a parallel world where everything is the same as his old one but yet different. For instance, he was not the Vongola candidate whereas his older twin brother Natsume is. And somehow,his reputation in Namimori is horrible and everyone hates him. How will Tsuna get through this? Is this life really worth getting reincarnated into? Disclaimer: I do not own KHR. Akira Amano does. But the plot belongs to me!!

"Re-Rene-san...?" The said brunet turned his head slightly, arms propped over his knees as he sat down next to the younger. The adult's tattered fedora shadowed his brown eyes as he gazed at the child. "Mm? What is it, Izuku-kun?" The green-haired child rubbed at his puffy eyes feverishly, looking up with teary irises, his lower lip trembling. "Do you...d-do you think...that I can become a hero?" Rene looked surprised for a second before his expression became neutral. Brown gazed into green eyes thoughtfully. Rene hummed before sighing. "No." Midoriya felt crushed and he ducked his head down, trying to smile. "O-Oh...." Suddenly, the child felt fingers wrap around his shoulder and he was brought into a one-armed hug. Rene flipped his fedora off of his head with his free hand before stuffing it onto Izuku's head, smiling gently. "Because I know you'll be something even greater." Izuku felt his eyes flood with tears as he tilted the fedora out of his line of sight to look up at Rene. "Y-You...really think so?" Rene chuckled, his usually dull eyes lit with genuine joy. "I know so." He replied softly.
