Let's recap friend by friend.
Hinata - Oblivious as fuck. Can't read the room to save her life, made up for her by her sheer enthusiasm and the force with which she sets up events.
Hirose - Wingmanning. Knows what's up with Takamine and Sakura, doesn't know what's up with Hatori.
Hatori - Ambiguous and go-with-the-flow style. Seems fine no matter what happens, focused on Hirose.
Takamine - Dense and cowardly. This adorable little idiot probably hasn't crystalized her feelings yet but instinctively places herself everywhere Sakura is.
Sakura - Not dense, but cowardly. Knows exactly what's going on but isn't doing anything about it either. Sakura! Take charge you idiot!
The handholding scene makes me think that Sakura is self-conscious in a way I wasn't expecting. Like, she's so aware I'm wondering if she's got some gay anxiety, as in afraid of how Takamine may respond to her gay feelings. So far this manga hasn't really felt like it would delve into that kind of a topic, but it's always a possibility.
