In Shu Ane

Hiroto is a studious young man trying to focus on his studies when his older sister arrives home completely drunk. Her presence is disruptive, but this time she has something else in mind than just being a nuisance.

Instead of letting him continue his work, she decides to take on the role of an unexpected teacher. She insists on giving him a very different kind of lesson, one that blurs the line between sibling teasing and something far more intimate. Her bold and forward behavior pushes their relationship into uncharted territory, leaving Hiroto to navigate the consequences of her drunken advances.
