Takuma, a university student who has just started living with his grandmother Fumiko, finds a university admissions guide in his late grandfather Eishi's study. It was a surprise for Fumiko that Eishi left behind. Fumiko takes a step forward and enjoys her days of "studying," a dream she had when she was young. Meanwhile, Takuma is unsure of his dream and worries about his future. The two of them find a mysterious mathematical formula in Eishi's notebook, who loved Mount Fuji.

A grandmother and grandchild suddenly find themselves living together.

Takuma (MAMEHARA ISSEI), a grandson who is confused about living together with his grandson, and his grandmother Fumiko (Ichige Yoshie), who was looking forward to living with her grandson, are also going to study at the same university! Looking at his grandmother Fumiko, who has a bright expression on her face as she says, "I came to make the dream of my youth come true," Takuma worries about "finding his dream"... Then the two of them come across a "mysterious mathematical formula" left behind by their late grandfather, who loved Mt. Fuji. This becomes another surprise that will motivate the two of them to take a step forward...

MAMEHARA will play the role of the grandson, Takuma Ando.

I'm really happy to finally be able to release this information to everyone.

It was a big challenge for me, and I thought about a lot of things and worried about how to create this work. I was really happy to be able to work with such famous actors and such a great director, and I think I was able to grow a lot. I hope that through this work, people can feel the joy of caring for someone and learning.

Please look forward to it.
