Well, that's a pity it turned out to be a scam. At least it was a fairly elaborate one, with even film staff, actors and actresses being duped into making it look more legitimate.
The Enishi and Takako relationship is a fun one. Both of them are kind of sad in a way (Enishi being a loser, and Takako generally being a failure despite how hard she tries), but I felt that it made their connection a bit more appealing. She keeps coming back to their inn to meddle and prove herself, and he relentlessly defends her. The both of them have grown more honest and mature as a result of this whole debacle.
It was interesting to see Yuina's grandmother and the other catty inn owners be so dismissive of Yuina. More interesting was her reaction to it. Yuina's eyes narrow and was certainly upset that so many adults have so little respect for her. She ran as fast as she could (which is amusingly still pretty slow) to check on Kissuisou.
I do wonder where Satsuki falls in this. She flatly states that it isn't her place to take over the inn, but her daughter was sent there and angrily returned to Tokyo to defend it, she's shown considerable interest in its well-being.
