They have been together since birth, but after enrolling in their current academy, a small misunderstanding created a rift between them. Once close, their relationship changed, and Haruhi's attitude toward her brother Sango took a turn for the worse. Sango, a serious-minded person, blames himself for the rift and silently endures, hoping they can return to the way they once were. One day, overwhelmed by his worries about their relationship, Sango even dreams of doing indecent things with Haruhi. Yet, in reality, nothing between them has changed. Will they carefully untangle the knots in their relationship and rebuild their bond? Or will they fail to recognize their feelings that have drifted apart, pulling too hard and tearing everything apart?

As her name "Haruhi" (which means "clear sun") suggests, she has a bright personality and is a cheerful, well-liked girl at school. Despite being twins, she and the protagonist look so different that people often point it out. Each time, she firmly insists that they are fraternal twins. They used to be very close, but at some point, Haruhi began to worry that always relying on her brother might be a burden to him. Troubled by this thought, she has recently started keeping her distance or adopting a more teasing attitude toward him. However, deep down, she can’t bring herself to truly dislike or push him away, leaving her stuck in an awkward, conflicted state. As a result, to outsiders, she ends up acting like an elementary schooler teasing their crush. This has only made things even more difficult for her brother, though she remains unaware of it.
