Kakashi is her ex but y/n is the sister of his student sasuke so they see eachother sometime and one day she goes to train but sees kakashi and his students also training
Y/n and kakashi are exes but they just cant let go of eachother, they always look at eachother for to long or y/n always keeps on training the same time he is teaching his students but everytime he sees her he smirks or just a small smile and even when they are standing close sometime they hold pinkys
