The city is very big, and people lose things every day, including umbrellas, necklaces, diaries...
Lost courage, lost love.
An amnesiac restorer who can sense the emotions of old things (actually very cute) vs. An affectionate father-type lost-item archivist (actually an heir to a top wealthy family)
1v1, he, light fantasy.
Intention: Love will find ways to come back to you
