The Beautiful Girl I Accidentally Helped Who Has Somehow Become Attached To Me.

Kirishima Rei, a self-proclaimed introverted loner who failed to debut in high school, inadvertently helps Mikami Hina, a top-tier beauty known as a "flower on a high peak." Grateful for the assistance, Hina expresses her desire to thank Rei, and unable to refuse, Rei accepts her gratitude. However, they both assume that this chance encounter would be fleeting—once the thanks are given, they would return to being strangers... or so they thought. To Rei's surprise, Hina grows attached to him, actively intruding upon his solitary life. As they spend more time together—during lunch break meetings, after school, in the mornings, and on weekends—Hina relentlessly invades Rei's daily routine. In a scenario where a loner and a high-class beauty would normally never intersect, the story of these two begins to unfold.
