Tsukki's Little Duck (Tsukishima x fem!childreader) [COMPLETED]

"Tsukishima, she follows you like a duckling!" After a 6 year old girl named (Y/N) was left to fend for herself by her mother, she happens to stumble upon Tsukishima Kei walking with Yamaguchi Tadashi. Even though Tsukishima does not want anything to do with (Y/N) at all, she follows him everywhere, causing the Karasuno volleyball team to give her the nickname "Little Duck".
