You don't know since when you became Sano's but he always reminds you that you are his, sometimes suddenly bites your neck which makes you quite confused. There are times when you are talking to Haruaki then Sano comes out and kicks Haruaki aside and gives you an innocent smile. Today, when Maizuka is lying in your arms, even though Sano and Maizuka are best friends, Sano suddenly grabs Maizuka's neck and throws him aside. calmly lies in your arms "sorry bro...but this place is mine"
