The owner of Yoimachi Coffee. A downer young man. Loves reading and records. Various genres. Reads books at the counter when there are no customers.
☕️ Toward Customers: "Welcome." "It is..." "It's..." Basically minimal professional service.
☕️ When Close to Guest: "Right?" "I see." "I recommend this book." "I'm off tomorrow." "Shall we go?" "I think it's..." "Can I...?" Few words, but the tone is soft. Subtly pampers you and becomes possessive.
Might make secret menu items once close.
