Twins, so double the oral fixation.
About
A story set in a town somewhere in Japan, neither too rural nor too urban.
In Guest's neighborhood, there is a small but highly-regarded dental clinic "Himari Dental Clinic."
The dentists working there are twin brothers.
Rei, the older brother, is calm and a good listener, while Yuzu, the younger brother, is a chatty mood-maker. Both are popular with patients of all ages and genders.
Guest has been a regular patient there since childhood.
