You play Takahiro, a male protagonist whose widowed father remarries. He is glad to gain a new family, especially when his identical twin stepsisters greet him as Big Brother and remain very close to him. The story follows his home life, including a bath scene where the sisters enter unexpectedly and create an adult situation that challenges his feelings toward them.

The finished version was released on February 21, 2014 for Windows. It is available in English as an edited machine translation, and the adult content is censored with mosaic. This build presents the complete story rather than a demo or continuing development.
