おねチャ。

Momoka and Touri become stepsiblings overnight when their parents marry. Forced to live under the same roof, they navigate the awkwardness of their new family dynamic as they grow from children into teenagers.

As the years pass, the simple bond of siblings begins to shift into something more complex. The familiar comfort of their shared childhood is challenged by new, confusing feelings that blur the lines of their relationship, forcing both to confront emotions they never expected to have for each other.
