Written in His Notebook is a high school-to-college romance filled with playful rivalry, unspoken feelings, and dramatic misunderstandings-blended with classic K-drama charm.
Liya, an introverted yet effortlessly charming artist, unknowingly captures the hearts of many, including the school's mischievous yet secretly smitten Milo. But instead of confessing, Milo annoys, teases, and flusters her at every turn, masking his deep admiration with playful antics. As the two navigate stolen glances, jealousy-fueled moments, and an intense school scandal, their story takes a heartbreaking turn, leading to years of separation.
When fate brings them together again in college, Liya is stronger and more confident, while Milo, still hopelessly in love, is determined to win her back. But can he mend what was broken, or is it too late? With swoon-worthy moments, heartfelt confessions, and K-drama levels of angst and butterflies, their love story is one that lingers long after the final page.
