She was Actually My Stepsister.: Recently, the Sense of Distance Between Me and My New Stepbrother is Incredibly Close

じつは義妹でした。 ~最近できた義理の弟の距離感がやたら近いわけ~

When their parents remarry, a high school student gains a new stepbrother named Akira. Akira is shy and reserved due to a difficult upbringing, but the protagonist, who has always wanted a sibling, eagerly tries to bond with him. They quickly grow incredibly close, their relationship blossoming with an unexpected ease.

The protagonist, misreading the nature of their growing affection, confesses their feelings, only to receive a positive response that deepens the misunderstanding. This confusion reaches its peak when the protagonist makes a startling discovery: Akira is not a brother, but actually a stepsister. Now, with their familial roles suddenly upended, Akira begins a new, flirtatious approach, aiming to transform their relationship from siblings into something more.
