Loving this show
After rewatching the last episodes, I then thought of something
Spoiler for I haven't read the novels, just a theory.. but just in case :):
I haven't read the novels yet.. But we confirmed on Episode 5 that Yui is indeed the owner of the dog Hachiman saved.
Then I noticed that the car that ran him over looked like it belonged to someone rich.. This latest Ep we find that Yukinon quite possibly belongs to a rich family.
Could she be hiding some secret connection with Hachiman as well?
Just a theory, we'll find out soon enough.. I guess
