May i introduce you to Acardis? :3
Acardis is a doctor in the interspace and has been around for a long time. Basically almost the beginning of the town. At first he worked in the hospital there but has made himself independent and is very happy with his office. He is known as "The Doctor who smiles" because of his warm and reassuring smile he gives people. He didn't always smile tho. In the beginning he always had a very serious frown on his face and over time coworkers and friends told him he should maybe loosen up a little. They said that some people are already scared of doctors and it doesn't help if their doctor is frowning like that. That was when he decided to pay closer attention and he did found a number of people who were anxious around him. So, he started to smile. It looked really forced at first but over time it became more and more natural and genuine and now it's as natural for him as breathing
