“Call of the Night” has two seasons, is relativly new and has romance without it being the main focus.

Monogatari series is quite long and is ecchi, but it is different from your “normal” anime so it is not for everyone. First seasons aired around 2015s if I’m not mistaken, but recent entries are around 2023ish. You need to look for watch order list to et the full expirience tho.
