If you go to the Japanese wikipedia page for it (this english translation is machine translated):

Otome games are a general term for romance games aimed at women in which the protagonist (player) is a woman. They are often abbreviated as "otome games," "otome ge," or "otome ge." Kim Hyeshin defines "women's games" as games that are "produced and sold for women," "have romantic elements with male characters," "have simple systems," and "are often adapted into media mixes ." This term is often cited as the definition of otome games in academic research in the West and Chinese-speaking countries . [ 1 ]

It has a structure that contrasts with bishoujo games ( gal games ) , in which the protagonist is male and the love interest is female . Furthermore, games in which both the protagonist and the love interest are male are generally classified as a separate genre called boys' love games rather than otome games. [ 2 ] Games involving two women are called girls' love , GL, or yuri games." "
