Hikari is always part of the group we gather. I never thought about her as a different gender, but after Hikari was confessed by my friend, something changed in how she looked. When she asked me if I thought she should date him, I pretended to be okay even though I really didn't want to. Around the time I started realizing my feelings, Hikari invited me. "Since I've decided to date him, let's have sex for the last time," she said.
