My Yuzu tree

My mother said to me,"Your memorial Yuzu tree have many fruit. Did you notice that?" I hadn't noticed ,so I went to see the tree in my parent's garden and I took a picture of it. There I took 3 fruits from the tree. When I showed Gonta the fruits, he was interested in them and he smelled them. But he had a fit of sneezing, so he wasn't interested in them. Maybe I guess the fruits of the tree will turn yellow after about 1 month.
