[Reducing Mosaic]ATID-432 Five years ago, I reunited with my ex-boyfriend that summer. From that day on, I started secretly meeting him behind my fiancé's back. Urala Hanaoto

Five years ago, my ex-boyfriend had been lingering in the corner of my heart. Even so, I was satisfied with my current life... and even got a boyfriend who was too good for me. We had greeted each other's parents, and I thought I would move forward that summer day when I accidentally ran into my ex-boyfriend. Since then, I've been distracted, and all I can think about is him... It was at that time. A single email arrived on my phone. The sender was my ex-boyfriend.
