Saegusa is admired by everyone. After retiring from being an idol when she entered high school, she quickly became the most popular student in school. She is smart, friendly, and always cheerful. Everyone sees her as perfect—someone who shines wherever she goes. But Takuya, a normal high school student working part-time at a convenience store, knows a different side of her.
One evening, while Takuya is working his shift, a suspicious-looking woman walks into the store. She is wearing large sunglasses, a hat, and a mask, as if she is trying to hide her identity. Her movements are strange, and she seems nervous as she browses the aisles. Takuya watches her closely, wondering if she might be a shoplifter.
Then, he realizes something shocking—the woman is none other than Saegusa!
At school, she is always confident and elegant, but here, she looks completely different. Her disguise is sloppy, and she is clearly trying too hard to blend in. But why is she sneaking around like this?
Curious, Takuya decides to observe her quietly. He notices that Saegusa buys instant noodles, cheap snacks, and soda—foods that don’t match her refined image at school. She also seems oddly excited about a limited-edition dessert, something she would never talk about in front of her classmates.
When she finally comes to the counter to pay, she recognizes Takuya and freezes. For a moment, there is silence. Then, she tries to play it cool, but Takuya can see her embarrassment.
“Fancy meeting you here,” Takuya says, amused.
The Idol Girl in My Class Is Acting Suspiciously Plot
Saegusa panics and quickly comes up with a ridiculous excuse. “I-It’s not what you think! I’m just… studying the latest convenience store trends!” Takuya knows she is lying but decides to play along.
From that day on, Saegusa continues to visit the store in disguise. At school, she remains the perfect, admired student, but at the convenience store, she lets her guard down. She talks about her love for cheap snacks, complains about difficult homework, and even jokes around with Takuya.
Slowly, Takuya starts seeing her not as the school idol, but as a normal girl who enjoys simple things. Meanwhile, Saegusa realizes that she doesn’t have to keep up her perfect image all the time—at least not around Takuya.
What started as a funny coincidence turns into a unique friendship. Saegusa’s secret is safe with Takuya, and in return, she shows him a side of her that no one else sees. As time goes on, Takuya begins to wonder—will he be the only one to know the real Saegusa? Or will she eventually show her true self to the world?
One thing is certain—behind her perfect smile, there is a girl who just wants to enjoy life, even if it means sneaking around a convenience store in a silly disguise.
