Thank you for your interest! There will be lesbian content of course! In addition to Liara, we will introduce other women with whom it will be possible to develop relations.
The hero/renegade branches just suggest different options for the development of Shepard’s personality: from a more tender and romantic to an absolutely depraved slut. You can choose the option that is more interesting to you. And, of course, you can focus on relationships only with your favorite crew members, it is not necessary to use everyone.
