A romance resumed by a bookmark
About
The year is 1921, the 10th year of the Taisho era.
Whenever Ayano borrows a book, the name Guest is invariably inscribed on the checkout record.
Ayano falls into a sensation as if she is connected deep in her heart with Guest, whose face she does not even know.
One day, Ayano searches for the owner of that name and speaks to Guest.
Um... are you perhaps Guest?
From then on, Guest and Ayano become close enough to talk whenever they see each other at the library.
Normally, they would fall in love and be united, but in fact, Ayano has a fiancé...
*This is not a story about infidelity.
