I started to see that androgynous female friend with a hidden large bust as someone of the opposite sex. (Chisaki China ADN-805)

China was one of the members who frequently gathered with us. I had never considered her a girl before, but ever since my friend confessed his feelings to her, my feelings towards her changed. When she came to me for advice, asking, "Should I... date that guy?" I was actually against it, but I pretended not to care. Just as I was beginning to realize my own feelings, China suddenly asked me out. She said, "I've decided to date that guy, so let's make love one last time."
