Does The Vexations of a Shut-In Vampire Princess have any canon relationships by now?

I'm looking for a new yuri LN series to get into and I know that The Vexations of a Shut-In Vampire Princess is marketed as a yuri harem series but at least in the first few novels it's supposed to be all one-sided. So my question is, does that change at any point in the volumes released so far (whether in the English translated ones or the Japanese ones without official translations)?

If it's all staying one-sided I'm not really interested so I wanna ask before I waste my time.
