[Again, a small pause from Hinata. What makes him really happy?

...Sonia's firm trust, Komaeda laughing like he's really happy, Souda divulging his troubles, Gundam 'sharing his power' with him, exchanging cups with Kuzuryuu, a look at Pekoyama's honest smile, even Teruteru dragging him about trying all manner of food...]

This is... probably going to be a weird answer, but... my friends. [A beat:] The thing is, I never had a lot of hobbies as a kid. I spent a lot of my time studying, all the way up until high school.

It was only after I met my friends that I really got to experience a bunch of things I had fun doing.
