Itazura na Kiss follows the story of Kotoko Aihara, a cheerful but academically average high school student who confesses her love to Naoki Irie, a brilliant and cold-hearted genius, only to be brutally rejected. Her life takes an unexpected turn when her home is destroyed and her family moves in with the Irie family, making her live under the same roof as Naoki. Despite his constant insults and aloof attitude, Kotoko’s unwavering determination and clumsy persistence gradually chip away at his icy exterior, leading to a decades-spanning romance that includes marriage and their life together as adults. Readers enjoy it for the classic “tsundere” hero, the humorous and heartfelt dynamic between the mismatched leads, and the satisfying slow-burn journey of Naoki learning to express his hidden affection.
