Ozaki Toshio and Sexuality (or not)

1) If you don't seem to care about a certain gender, does that mean you're not interested in that gender, in the way that your sexuality will exclude that gender?

2) Just because you happens to love someone the most, does that automatically mean you harbor romantic feelings for said person? Does that mean you're into their gender in the first place?

( Ono has implied stuffs, but what do stuffs actually mean? )
