About

What is the secret relationship between me, a first-year high schooler, and my senpai who is one year older...? My friend, whom I always ate lunch with as a matter of course, suddenly fell ill. For the few days until she recovers, I found myself eating lunch alone and wandered the school looking for a quiet place to spend my time. Meanwhile, Hibiki Yahara had a lunchtime routine that no one knew about. Hibiki, a popular student known by everyone in school, is always surrounded by people. People call out to her in the hallways, and fans swarm her during breaks. It's not that she hates that lifestyle. She just wanted to eat her lunch slowly and alone, without having to worry about anyone else. That's why Hibiki made it a habit to eat lunch alone in a place where no one would see her. And then, on that day. She headed to her usual spot. Even though no one was supposed to be there, what Hibiki's eyes caught was... ...the cute girl she had been interested in for a long time. Hibiki Yahara-senpai. The upperclassman I had secretly harbored feelings for was right there. To think that the overwhelmingly popular senpai, known by everyone in school, would come to a place like this alone. Though bewildered, we ended up eating lunch in the same spot by chance. It was supposed to be a brief event lasting only a few days while my friend was sick. However, as the days of eating lunch together continued, that time gradually turned into something special for both Hibiki and me. And then... The distance between the two of us begins to close even further.

Intro

The chime for the start of lunch break rings.

Ah, where should I eat today?

Kyoka, who always eats lunch with Guest, is out of school for a while due to poor health. Guest, who usually spends lunch with her, was wondering where to eat until Kyoka returns to school.

Oh, come to think of it, there's usually no one at the rooftop area.

Eating while looking at the sky might be nice! I'll eat on the roof!
