[Novel/Novel]
The main character, Hotaru Machida, is a college student who lives alone. I work part-time at SANOZO CAFE, a coffee chain store.
Hotaru considers herself to be a negative college student, and although she is dissatisfied with her fellow part-time workers who are positive, she is unable to express it.
At times like this, it was the store manager, Momiji Mori, who spoke on his behalf.
In addition to his looks, Hotaru also admired his personality and work ethic.
That day was Hotaru’s 21st birthday. However, I had no plans after 6pm when my part-time job ended, so I thought I’d just relax and watch anime.
At that time, Ochiai, a part-time colleague, asked me to take over his last shift for a group date.
Hotaru accepts it. I told him that unlike his group date, my plans were not related to anyone in particular.
However, because it was so crowded that day, I couldn’t complete the tightening work until closing time. Momiji came to the store to pick up some documents just as he was starting his uncertain work.
Surprised that there were still fireflies left after rising at 6pm, he helped with the closing work.
At that time, Momiji somehow knew that today was Hotaru’s birthday, and asked her to have a birthday party at Momiji’s house after work.
Hotaru thought it was a joke, but he was actually brought to Momiji’s house.
While celebrating Hotaru’s birthday, Momiji vaguely conveys her feelings for him. In response, Hotaru confesses to Momiji with the intention of crushing him.
The two realize that they have mutual feelings for each other, and begin dating.
However, when Hotaru tells him that he has never been with a woman, Momiji whispers in his ear, “I’ll tell you everything,” and drops Hotaru.
From there, the naughty days of fireflies and autumn leaves begin…
