Under The Cherry Blossoms (Ereri/Riren AU fanfic)

Levi is a lonely man, living in the middle of nowhere.
The only thing he has apart work, small house and a cat, is an abandoned old garden with a big cherry tree in the middle. This is where most of Levi's free time is being spent.
The man holds painful memories from the past and asks himself if he'll ever feel the warmth of human's love.

One day, a brown haired teenage boy slips into Levi's garden and thus, the story continues with them together.
