I recommend Jongno Hanbit Clinic.

It's a hospital like our neighborhood primary care doctor, where you go when you have various illnesses and to regularly pick up necessary medications.

The director is an older female doctor who seems a bit aloof and strict, but also a bit tsundere. I like that she speaks frankly. Since the hospital keeps records of my health, I can't help but trust it. These days, hospitals without popular departments are gradually disappearing, which is really concerning. Internal medicine isn't as popular either, but I hope that departments dealing with life are able to survive more nobly. Personally, I trust internal medicine more than family medicine, but there are only a few clinics like that in the neighborhood. Dr. Hanbit Internal Medicine Clinic, please continue to treat patients for a long time~~
