They mentioned they got another ham from Dad in the summer rolls chapter. They probably get a new one every few months since they can apparently afford it.
I don't like the anime's character designs. The manga's faces are precious little squished potatoes, while the anime's look like the sides of their faces were pinched in to make their heads taller. It's a small change, but it loses a lot of the charm that made me like the designs.
I re-read everything from the beginning, and the drama part feels a bit more natural that way, not as rushed or out of place as it did at first.
It also reminded me just how much I like Minami's tattoos. That shot of her bare back in chapter 1, wow.
