"What meaning is left in life when your reason for living disappears?"
On the morning of March 14, 16-year old Amano Shizuka's life teeters on the brink of ruin when she lost her most cherished person -the light of her life- to the clutches of death.
Her heart falls into a frigid winter while flowers all around her begin to bloom to greet the incoming spring.
Shizuka, however, isn't the only one who seems to have been forsaken by spring's joy.
A younger sibling takes on more burden than he was supposed to originally bear. A twin dedicates his life to another's happiness, forgetting to live his own. A genius, as if cursed, keeps chasing afterimages of the past. An orphan finds less and less meaning in life with each passing day.
As if bound by a thread unseen by the eyes, Shizuka and these people's paths tangled.
Will she choose to grab hold of these threads? Or will she choose to let go?
