Rui ni Tokimeku Hazuganai!

For as long as she can remember, she has viewed her childhood friend as nothing more than a younger brother. Their relationship has always been defined by comfortable familiarity and the easy dynamic of growing up side by side. She never once considered him in a romantic light, assuming their bond would forever remain safely within the boundaries of platonic affection. To her, he was simply someone to look out for—a constant presence rather than a potential partner. However, that long-held assumption is suddenly shattered when he steps forward with an unexpectedly direct confession of love. Without hesitation or ambiguity, he makes his true feelings known, completely dismantling the sibling-like dynamic she had taken for granted. This straightforward declaration leaves her entirely caught off guard, forcing her to confront emotions she never anticipated feeling. Now, she must navigate the sudden shift in their relationship, grappling with the realization that the boy she always treated as family is determined to become something far more significant in her life.
