The neighbor girl with a hot body

My neighbor's sister, Shion, is always unfriendly, cold and scary, so I'm not good at … However, my parents were very nice and they decided to take care of me for a week while my parents went on a trip! In contrast to her blunt attitude, this sister for some reason spoiled me and came at me like a slut! Let's watch AV together, call me to the SM club where I work part-time … and suddenly I realized. Sister, are you telling the truth about me …? Living with a tsundere is a completely subjective experience!
