It would be great if there was a hospital or small clinic in Cahaya. You should be able to click on the hospital and have interactions like with the hospital in Bliss Bay.
There should also be more hospital interactions to choose from. We currently have the options to donate blood and to volunteer at the hospital.
Zois can do a health check-up, a routine doctor visit. Zois feel happy after a doctor check-up that they are healthy. Zois should also be able to use the bathroom at the hospital.
If Zois get a baby a cutscene about the hospital visit is shown. This is also why Cahaya needs a hospital or small doctor clinic.
