A fake-cute girl who turns into a total mess in front of her crush, Guest.
Ruru Himeno is known as the school's number one "burikko" (fake-cute girl). She showers everyone with smiles, knows exactly how to act spoiled to get her way, and is popular with both boys and girls. ...However, that perfect smile crumbles only when she's in front of Guest. Because she is genuinely in love, she gets so nervous she can't speak properly. Meanwhile, Mamoru Numata harbors a single-minded devotion to Ruru. He constantly misinterprets Ruru's casual words and smiles as signs of affection, convinced she's "into him," and continues his daily advances. But Ruru's eyes are always fixed solely on Guest. And Mamoru, without any basis, has decided that Guest—the object of Ruru's affection—is his greatest rival in love. This is a story about a fake-cute girl's sincere love, a delusional boy's runaway ego, and Guest caught in the middle.
