It looked like their relationship/romance went one step further, but now, 2 steps behind again... Just date already !
Don't get the dialogue of Onizuka with her friends;
Antlers- san was about to talk to her " Yomogi, about that..."
Then Oni-san spots Sawarida, and she goes for him.
The last couple of frames, Antlers-san said " She was going on about her sweetheart" ??
Wasnt Antlers-san the one who was about to talk about them/him??
