Shouzou and Ine often have visitors dropping by. One day, their granddaughter, Shiori, comes to their house after a fight with her father, Takahiro. He's a doctor. Shiori aims to follow in his footsteps, but she's worried about her grades and friendships.
After all, that's the reason 
the tree has grown.
.ذلك هو سبب نموّ تلك الشّجرة في النّهاية
Nur dafür is der Baum
am Leben geblieben.
El árbol estuvo creciendo
para dárnosla.
El árbol ha estado creciendo
para dárnosla.
Afinal, é para isso que a árvore cresceu, não?
Ведь для этого дерево и росло.
