Book review

Teddy bear.
This is love story.
This story's hero is Seiya and heroine is Haruna.
Two people met you in a certain town and fell in love all too soon.
However, he suffered from a unidentified disease.
It was Alzheimer.
As a day passes, as for the disease, memory gradually fades away.
He has begun to gradually get rid of memory.
However, even if forget any kind of other things; needed to never forget only her thing.
There was the teddy bear which I got from him before by pillow of a bed of her room.
She fell asleep while always holding the teddy bear when she was lonely.
The stuffed toy seemed to totally do his change.
