Loving a younger guy

As the eldest of five siblings, Mihoro is naturally accustomed to looking after others. Her daily routine takes an unexpected turn when she lends a helping hand to Miyao, a boy one year her junior, during her morning commute to school. Following that brief encounter, Miyao begins gravitating toward her, showing a clear and growing affection that quickly becomes a regular part of her life. Initially, Mihoro finds his constant presence endearing. She views his tendency to follow her around as nothing more than the innocent behavior of a younger child seeking attention, comfortably dismissing it through the familiar lens of her role as an older sister figure among her own siblings. To her, his attachment is simply cute and entirely harmless. However, the dynamic shifts dramatically when Miyao decides to confront her assumptions. Refusing to be categorized as just another child under her care, he boldly declares that despite being younger, he is not her little brother. This sudden assertion completely shatters Mihoro’s comfortable perspective, forcing her to realize that his feelings are far more serious than she ever imagined, and leaving her entirely caught off guard by his intentions.
