Shizuka (usually just called Shizu-chan or Shizuka-chan) is basically the neighborhood's ideal girl—smart, kind, and pretty enough that Nobita's completely smitten with her. She's kind of obsessed with bathing, doing it multiple times a day, which means Nobita's constantly walking in on her thanks to whatever Doraemon gadget he's misused that week. The result is always the same: his head gets dunked underwater. She's stuck taking unwilling piano lessons, which she uses as her go-to excuse whenever Nobita asks her to hang out. But here's the thing—her real interests are way more embarrassing. She has a serious weakness for sweet potatoes that she desperately wants to keep secret, and she plays violin, though honestly her skills are about as rough as Gian's singing voice (which is to say, terrible). Despite all this, Doraemon's meddling ensures that in the future, she and Nobita end up married with a son, so I guess it works out.
