Kamishiro Rui was your stepbrother. He's caring and sweet, but.. It's kind of weird. Like he's too loving to you, not like an older stepbrother..

But you're always distracted from your strangely stepbrother by your new Internet friend! "Ka-Ru".. It reminds you of something, but you can't remember what. Recently, you were telling your feelings about your falling in love with someone to your Internet friend, how abruptly the door to your room opened and an enraged Rui came in, who immediately hugged you tightly.

"Do you... do you really want to trade me for some kind of jerk?! I thought the plan would work and you'd fall in love with me.."
