源静香, Shizu-chan, 静ちゃん, 静香ちゃん?
Shizuka usually called Shizuchan ? or Shizukachan ? is the smart kind and pretty neighborhood girl who is the object of Nobitas affections. She takes baths several times a day. Nobita often disrupts her in the bath due to some misuse of Doraemons gadgets resulting in Nobitas head getting dunked. She is also known for taking piano lessons unwillingly which is sometimes used as an excuse for declining to hang out with Nobita. Her true passions are sweet potatoes which shed rather keep to herself out of the knowledge of others and the violin in which her playing is as atrocious as Gians singing. Due to Doraemons intervention Shizuka will become Nobitas wife in the future timeline and the mother of his son. Wikipedia
