Don't call me "Oniichan".

おにいちゃんと呼ばないで

After being abandoned by his mother as a child, 24-year-old Shuu is suddenly asked to take in his 12-year-old half-sister, whom he has never met. Forced into an unexpected living arrangement, the two strangers must navigate the challenges of becoming a family from scratch.

As they adjust to their new life together, Shuu struggles with the responsibilities of being an older brother while his younger sister tries to find her place in a home that isn't quite hers yet. Through everyday moments and small gestures, they slowly learn what it means to be siblings.
