[Otome Game] Gender Is Such a Little Thing

The protagonist of this story is Du Hui Takuya, the youngest of three siblings.

His family consists of his parents and two older sisters who are rarely home...

...Well, that's what Takuya thought for a long time.

"Damn it!! There aren't any women in my family at all!!"

After he learns the truth, he probably ends up saying something like that.
