After leaving Soul Society and all the hurt in his life, Hitsugaya Toshiro learned to live peacefully with Hyōrinmaru in this world.
Drink a cup of tea, read a book, and let a story grow gently at their feet.
From ignorant friction to the most touching attachment.
They understand each other until they can no longer be separated from each other.
This story just goes on warmly.
There's no trickery involved, just everything about the tenderness between Hitsugaya Toshiro and Hyōrinmaru.
