I’m basing a tv show off of this:

Normal person has overexcited best friend Chase who supports them unconditionally and demands they go on walks with at random times, dog friend works at the fire department

And Sheila the disaster friend who sleeps 12 hours a day on our couch, has no job, and everyone is all partly in love with due to how strange, beautiful, and youtube famous she is

These are already characters tho, on Brooklyn99. Charles Boyle and Gina Lanetti

you are… extremely correct
