Zhu Zi's gaze shifted to Reina Matsui.

"Matsui, have you thought about it, are you sure you want to graduate?" asked Zhu Zi.

"Yes, Teacher Zhu Zi. I've figured out that it's time to leave, and no matter how difficult it is for a person, I have to choose to persevere. Reina Matsui said firmly.

"Now that you've thought about it, let's go. I believe in your strength, and I also believe that Mi will not disappoint us all. For so many years, it has been hard work both in AKB and in Nogizaka. Zhu Zi said with a smile.

Reina Matsui secretly breathed a sigh of relief in her heart.

The members of Nogizaka are a little reluctant to graduate with Reina Matsui, but they also know that this is a path they must go through in life.

It's just that Reina Matsui graduated before them.

"Teacher Zhu Zi, thank you for taking care of you for so many years. Aligado!" Reina Matsui bowed deeply and thanked Zhu Zi.
