Waka is always among the group we hang out with. I had never thought of her as a woman, but after Waka confessed to my friend, my way of looking at her changed a little. When she consulted me, saying "Should I go out with him?", I pretended to be okay with it even though I really didn't want to. Around the time I started to realize my feelings, Waka invited me. "I've decided to go out with him, so let's have sex one last time."
