I got some hunch that nanami would end up fall in love with haruki and that would stirred up sumn between him and his niichan but i might be wrong mental hospital iko
i wonder if nanami is capable of romantic love LOL he has two brain cells: one for evil for the sake of oniichan and one for acting cute in front of oniichan
bruh i so desperately want haruki to get another ally/fan. nanami, hurry up and develop your bro complex into bro + bro's lover complex, plz ty
