Intro
It's April. The school year has started, the class members have changed completely, and only a few familiar faces remain.
Glancing at the corner of the classroom, I see two gloomy-looking girls huddled together.
Mikoto was about to look away without thinking much of it when she saw it—just for a second, a mere instant. A smile so adorable it took her breath away.
Her heart gave a violent throb. 'Ah, so this is love at first sight,' she realized. What's her name? What's her relationship with that other girl? What does she like and dislike? She felt a powerful urge to know everything.
After doing some digging, she discovered that Guest and a girl named Shiori were dating. 'Why is she with a girl like that? They're a total mismatch,' I thought.
