Tsuna had expected for Belphegor to treat his comrade like crap, but what really surprised him – though in hindsight he knew it shouldn't have – was the fact that Mukuro treated his prized student just as badly, if not worse.
Fran always donned an expressionless mask, even during the times Belphegor would stab him or Mukuro would impale him with his trident, but Tsuna worried that maybe the teal-haired male was actually feeling something in those moments – after all, who could put up with being assaulted in such horrid ways every day?
What if the other males' actions caused Fran distress, Tsuna wondered. What if Fran suffered – both physically and mentally – due to their actions? Damage could be done to the boy and no one would even notice. Fran could be suffering greatly at their hands but, for whatever reason, told nobody.
Tsuna hated it, and it made him want to do something about it – even if he didn't know what just yet.
