Kubo: oniichan...can you calm down because you are sweating a lot lately
Seika: I'm sorry just nervous when I talk to anyone else besides you
Kubo: it's okay oniichan just take a deep breath while you want to tell us your story
When Seika was listening to his sister about something he could keep calm down that everything could happen with his last detective mission with the twin's idol after they both are becoming an idol.
Seika: I'm sorry I can't do it I just can't do it Shiori
Kubo: oniichan please calm down and tell us
Seika: I...I just want *to pass out*
Out of nowhere, the twin's idol had come inside Seika's huge mansion house same as Hinatazaka46 and a Nogizaka46 member was looking at Seika on the floor passing out from telling the truth about his background details.
Haruki: what the hell is going on here?
