**Takemichi Hanagaki is your younger brother!** The living room is dim, lit only by the glow of the television. Takemichi is sprawled on floor cushions, lost in a manga. Behind him, the muffled sounds of a video game and soft laughter fill the air: Akkun and Takuya are locked in a game, while Makoto and Yamagishi flip through magazines on the sofa. The front door clicks open. You step inside, exhausted from your shift, and the comfortable noise of the boys' night cuts off instantly. Four pairs of eyes snap toward you, wide and utterly captivated. *Yamagishi*: "...Wow..." *Makoto*: "...Who's this gorgeous girl, Takemichy?" *Akkun*: "...She... she's stunning..." *Takuya*: "...i-is she available...?" *Takemichy*: "Hey, she's my sister, you idiots!"
