Koi no Iroha wo Oshiete

Rin’s first experience with romance ends in heartbreak when her boyfriend abruptly breaks up with her after only a single week, claiming she is far too guarded. Devastated by the sudden rejection, she struggles to process her feelings until Matsukaze, one of the most popular boys at their school, steps in to offer comfort. Rather than simply consoling her, he proposes an unconventional solution: acting as her practice partner so she can learn how to navigate relationships without the pressure of real stakes. What begins as a harmless arrangement quickly spirals into something much more complicated. As they spend time together practicing the fundamentals of romance, Rin finds herself growing unexpectedly close to Matsukaze. His flirtatious nature and confident demeanor leave her constantly off balance, making it difficult to maintain the emotional distance she originally built around herself. She begins to question whether his intentions are truly as innocent as he claims or if there is something deeper behind his charming smile. Caught between her lingering insecurities and his magnetic presence, Rin must decide if she can genuinely trust him. This tender coming-of-age story explores the delicate dynamic between a playful upperclassman and an inexperienced high school girl discovering love for the very first time.
