Nanami contacts me after we have not seen each other for eight years since college graduation, inviting me to a gathering on the night before a classmate's wedding. We used to be friends with benefits, so I leave without telling my current girlfriend. Eight years ago, we also secretly fucked again and again behind my girlfriend's back. As our meeting approaches, I wonder whether Nanami remembers those days—or contacted me because she wants to rekindle what we had.
