Cowpoke
I always had this difficulty in locating them, the other NPCs seemed to be fine, but whenever I need to talk to them, dang, I can't find them or I go out too late of my farm (Tho Harvey is just mainly at his clinic). Aside from it, I never had the vibes when I first saw them.Why?
In the long run, I would still marry them on different saves because I want to see all of their cutscene/events.
