Pretty sure the reason it's yuri is cuz of the author. She tends to prefer yuri and even Jahy-kun has the other female characters crushing on her. (I'm hoping it goes in that direction too, preferably with the restaurant owner) I don't think she would have wrote this with an older male character as a butler, it just doesn't seem like her. As for me I really like this side couple and was hoping for one-loli the moment she first appeared.
