Who thought Sakurama would be Doppel-san and Hattori-san's wingman?!? Thanks to her, we saw Hattori's wonderful smile!
Hattori and Yamamoto definitely needed someone else to kickstart them communicating again, and it just so happened to be Sakurama who did it, though perhaps it should have been Hashimoto-sensei. Sakurama at least bluntly told Hattori to start being honest and start talking. And because they did, there was no longer any misunderstandings. A quick resolution!
