It's cold outside, and Shu-Kun asks to use her bathtub for a bit. She's not sure if it's a shower or a bath, but she wants to go to a nearby spa. She wants to use the hot tub, too, but Shu says it'll be a while before it gets hot enough to use it. She also wants to try the "super sento" , which is basically a fancy hotel with a sauna and steam room . Shu says she saw an article about it on the internet, and wanted to try it out. Shu asks if she has a tattoo on her hand, and she says she doesn't, but that she'll have it on for a couple of weeks. Shu also says she's got a weird bruise on her shin, which Shu says is a hickey . They go to the spa and Shu says he feels like he's "eating beef tongue" . He says he wants to eat the hot water, but he can't because his feet are already hot. Shu then asks if they can eat ice cream at the spa. They say they're not allowed to eat in the area, so they'll just go to Shu's place to have baths. Shu wants to be the caretaker for her friend's daughter, who's getting a scrub. Shu thinks she smells gross, so she sniffs around for dirt. Shu and Shu say they want to go back to their hotel for a bath before they go home for the new year. Shu insists he'll go home, too.
