My little sister loves me so much it’s scary… no, seriously. My sister—Namiki Shuri, is definitely a very charming girl. She’s got intelligence, she’s got beauty, she’s got style. But just look at me, I’m just some extra-ordinary mob. Now the problem I’m facing is that this sister of mine loves me way too much. In my third year of middle school, I found the Onii-chan Notes in Shuri’s room: A detailed log of my every behavior. Not to mention when she was usually so cold towards me, lo and behold, she was head over heels in her notebook. Oh, let’s not forget, my discovery that there were surveillance cameras and listening devices hidden around my room…! In the summer of my second year of highschool, I learned of Shuri’s plan to ‘Lock up Onii-chan, and make it so he can’t live without me’. I made my decision. Then and there.
