Unless you watch hololive, and specifically her, it's normal that you don't know. To make people understand it better, she is the equivalent of big tiddy goth gf. The only difference is that she is not goth, but she has big breasts, she's horny almost 24/7, she has unusual fetishes (like smell), she comes from a dysfunctional and poor family (thanks to this she may have trauma; incest), she is very affectionate with her genmates and from time to time she brings out her crazy side (it's not like "uwu she crazy lul kawaii", sometimes she talks about certain topics or makes comments that make you wonder if she's okay). Many times she spoke about her brother in terms as if he were her boyfriend, and that's how she sees him around her. She even makes jokes that are half true in which she says that she is attracted to him. Also, if you keep in mind that in Japan these types of traumas or fetishes are more common, well, you get the point. "Future husband" is also bs. She has lesbian, or at least bi, tendencies. Some time ago she made a very serious announcement asking people not to get in the middle of a relationship with a genmate/friend, a friend with whom they bought rings "pretending" to be married. Her closest Hololive circle, knows this facet. Maybe they don't know the details but they definitely know that she makes spicy content. I don't know, taking all that into account, I don't think she'll ever be doing R18.
