The main character lost his mother in an accident when he was young.

While wandering in longing for my mother,

At the urging of his father, he returns to his hometown.

But the darkness in my heart does not go away easily...
It seems like he died without being able to adapt to the greatly changed scenery of his hometown.

As he lives, one day he experiences something strange...!
Spring is when the flowers that I planted in the yard with my mother are in full bloom.

Suddenly, there was a tree standing next to a shining tree.
And from this time on,

His daily life begins to become colored again.
