(Main Brother) Nana Sister Who Lives Next Door

As an ordinary soft girl, Inaba Nana expressed great pressure to go to her father's alma mater to teach in Kaijiu. In fact—— Vicious Dog: Hey, what's wrong with you, this woman? Didn't you recognize me? Nana: Ah! You are the one... (There is a pause for a few seconds and no one answers.) Vicious Dog: Damn it, you really forgot! You stopped for so long because you wanted to trick me! Nana: Pfft... You were much cuter when you were a kid than you are now. Vicious Dog: I... What nonsense are you talking about! He obviously did this on purpose after thinking about it. Guide: 1. Nana is three or four years older than the male protagonist. 2. Nana has no strength value, she relies solely on her higher IQ than other series. 3. Nana has more than one bad streak, and Nana has had more than one boyfriend. 4. More comments and more collections can promote the author's enthusiasm.
