Gimainara Honki ni Nattemo ii yone?

義妹なら本気になってもいいよね?

Masato Kyoki never got along with his own sister, Yurin. Their relationship was cold and distant, until their parents drop a bombshell: the two aren't actually blood-related. The revelation shocks Yurin so deeply that she loses all her memories of Masato.

After she is released from the hospital, Masato worries about her mental state. But to his confusion, Yurin's attitude has completely flipped—she now acts much more intimate and even seems to be coming on to him. Unable to understand her sudden change, Masato finds himself getting flustered by his new, affectionate stepsister.
