Nope, not since I unlocked all the patterns. It's weird that there is only one NPC you can chat with. I wouldn't remember even if I cared to.
I just like her because I've seen her in multiple games and I love how her personality has grown over the series! At first she was snobby and not close to her sister. But she's slowly become nicer and closer to her sisters, while still pursuing her own dreams.That's a good point. I wish other NPCs had more dialogue like Sable.
I enjoy checking in with Sable but I haven't heard her talk about cherry blossom season. I don't like it when she talks about Label though. I'm not a fan of Label. I would like Label more if she worked in the shop with her sisters and didn't ask me to do silly fashion challenges.
