Well, chapter 1 could potentially depict how they first met or maybe a significant challenge they face together as a couple. It could set the stage for the rest of the story.
Maybe it's a story about their adventures, facing challenges and having fun. Or perhaps it focuses on their wisdom and experiences passed down to younger generations.
Dear grandparents,
Hello! I'm your grandson/granddaughter, and I'm writing to express my thoughts and blessings to you.
Ever since I left home to go to school, every time I think of my grandparents, my heart feels especially warm. Although there are many troubles and difficulties in school life, you are always by my side to support me and give me encouragement and strength. I want to tell you that I am very grateful to have relatives like you. I will continue to study hard and be a good child to make you proud.
Grandpa, Grandma, you're all very healthy. I envy you very much. I hope that one day, I can personally accompany you to your old age. I hope that you can always maintain a healthy body and a happy mood to enjoy a beautiful life in your later years.
Finally, I want to say "sorry" to you because I always delay writing to you and let you wait for me for a long time. But I know that you have always supported me, and I will continue to work hard to reassure you.
I wish you good health, happiness, and happiness!
To your grandson/granddaughter.
sincerely
Salute!

The experiences could vary greatly. They might be involved in a community event that brings people together, or they could encounter unexpected visitors that change their lives. It all depends on the creativity of the manga author!
One story could be that the mom, grandma and grandpa go on a family trip together. They visit a beautiful countryside, explore old farms and share memories of their own childhoods while enjoying the fresh air and natural scenery.
A story could be that the mom was raised by grandma and grandpa. They provided love and support during her difficult teenage years. Grandpa was always there to give her advice on school and career choices, while grandma was the one who comforted her when she had her heart broken. Their relationship is one of deep love and gratitude.
I'm not sure about the specific release date. You might want to check the official anime website or related news sources for the most accurate information.
