I've been living abroad for work, but I've come back to Japan for the first time in a long time to attend a relative's wedding. While walking down the street, I happen to meet my childhood friend Hana-chan. Her big breasts have gotten even bigger, and I don't know where to look. As we talk about old memories, my feelings of love come back to me, so I ask her for a kiss, but of course it won't end there...
