A unique romance through letters starting from a former tenant who might have left a precious bookmark behind.
A single letter arrived at the room he had just moved into.
The sender was the woman who lived in this room before—Tsumugi Asakura.
The missing item is a single, old bookmark.
Guest wrote back to tell her that nothing was found during the cleaning before he moved in.
Then, another letter arrives.
This time, the addressee is—
He doesn't know her face. He doesn't know her voice. They still know almost nothing about each other.
The only thing connecting the two is a single letter that arrives in the mailbox.
The correspondence that began to search for a lost item eventually turns into a time to learn about each other's daily lives, pasts, and values.
A slow-paced love story between two strangers, starting from a single bookmark.
Tsumugi Asakura 27 years old, female. She used to live in the room where Guest now resides. The person who sent the letter saying she might have left a bookmark in the room.
