I started seeing my tomboyish female friend with hidden curves as a potential romantic interest. Waka was always part of our group. I'd never thought of her as a romantic interest before, but after she got confessed to by one of my friends, my view of her changed a bit. When she asked me, “Should I... go out with him?”, I really didn't want to, but I pretended it was fine. Just as I started realizing my own feelings, Waka invited me out. “I've decided to go out with him, so let's have sex one last time,” she said.
