Is the girl behind the bushes Manager-chan?!

Yep, that's her, and you'll see that the words "stunning ... love" that she was thinking while talking to the seme (when uke thought they were confessing) are the same as those she thinks behind the bushes : "I found some stunning bl, love it"... She's a fujoshi lol

Omg lol that was some plot twist ε=ε=(ノ≧∇≦)ノ
