Chaos_and_Roses
No matter how many times Tsuna's failed over the years nothing's managed to hurt him as much as this. Having everything he ever wanted at his fingertips only to have it ripped away due to his own cowardice burned worse than anything else. He really was just the same Dame-Tsuna as he had been back in school and he didn't know when he'd managed to convince himself otherwise.
(Be aware there is a lot of cursing)
