Yukino Miyazawa is a Japanese high school freshman who is the envy of classmates for her good grades and immaculate appearance. However, her "perfect" exterior is a façade, a charade she maintains to win praise. In the privacy of her own home, she is spoiled, stubborn, and a slob, and studies relentlessly and obsessively to maintain her grades. On entering high school, she is knocked from her position at the top of the class by Soichiro Arima, a handsome young man whose very existence Yukino considers a threat to the praise on which she thrives, and she vows to destroy him. When Soichiro confesses that he has a crush on her, Yukino rejects him then boasts about it at home. Her observant little sister Kano points out that her rivalry with him comes from admiration, causing her to rethink her own feelings.
Before she can figure out if she hates or likes Soichiro, he visits her home and discovers her being herself. He uses the information to blackmail her into doing his student council work. At first Yukino accepts it, coming to realize that he is also not the perfect student he pretends to be. Tired of being used, Yukino revolts and Soichiro apologizes, and admits he still loves her and just wanted to spend time with her. Yukino realizes she loves him as well, and together they resolve to abandon their fake ways and be true to themselves, though she initially has trouble breaking of her lifelong habit of pretend-perfection and her competitive ways.
As the series progresses, Yukino is able to open her true self to others and earns her first real friends beyond Soichiro. It is eventually revealed that Soichiro was striving to be perfect in order to avoid turning "bad" like the parents who abandoned him. Falling in love with Yukino, he is able to become more true to himself, but he also finds himself becoming increasingly jealous of Yukino's change bringing new friends and new activities into her life, and of her having parts of her life that don't involve him. When Yukino unknowingly hurts him, he becomes even more jealous and afraid, and begins to wear another facade of the "perfect boyfriend" in an effort to protect her from his "ugly" self.
The return of both of his parents into his life sends Soichiro into a dark area, but helps him finally break free to truly be himself as Yukino and their friends help him learn to lean on and trust others. The end of the series shows Yukino and Soichiro in their 30s, with their three children, and gives updates on the various friends they made along the way.
