When Tatsuya was inside his secret basement floor with a hidden room but he didn't notice at Nagi wanted to visit her brother and she can't visit Nii-chan just yet because she has three shows to shoot with her.
Back at the Nogizaka studio, there was Umezawa Minami who was disturbing her from finding the truth about him as a spy agent.
Later Umezawa was calling someone on her it was Tatsuya and she was talking to him.
Umezawa: sorry sir but after Nagi finishes the three shows she wants to visit you
Tatsuya: what! but she can't find out that I am really the spy agent and you too as well
Umezawa: yes of course but what can I do next?
Tatsuya: stays with her don't let her leave
Umezawa: of course sir
They ended their call to each other while Nagi see that the 3rd gen Member are ready to go with the 5th gen Member but Nagi noticed that Umezawa was talking to someone on her phone.
Nagi: Umezawa who are you talking at your phone?
Out of a sudden, Umezawa has to lie to Nagi and she was saying to her was something stupid to her.
Umezawa: I was talking to your brother and guess what he say?
Nagi: What did he say to you?
Umezawa: he says that he wants to you him at his house
Nagi: did he miss me?
Umezawa: well maybe
They just went with the 3rd gen Member inside the bus while we go somewhere to the place where we go and have fun together with them.
Back at Tatsuya's house later he had a text from Umezawa saying a stupid thing to his sister that was.
Umezawa: sorry sir I think to saying the wrong to her
Tatsuya: what did you say to her?
Umezawa: I said to her was that can visit you at your house
Tatsuya: fine you do your job done but I need to tell her myself and you come home too
Umezawa: yes sir I'm sorry
Tatsuya: it's okay you did well
When Umezawa deletes the text and she turns off the phone and takes out her extra phone full of fake news on the website and shows Nagi that.
Nagi: so Senpai what did you watch there?
Umezawa: so Nagi sorry I'm watching some news early this morning
