Someone who identifies as quasiromantic may see their attraction as non-traditional or may feel it differs from crushes, perhaps a mix between platonic, romantic, aesthetic, or somewhere completely different and/or it involves other non-traditional aspects, such as rare attraction, or attraction but non-physical, non-platonic but romantic, etc.
the sexual counterpart is quasisexual, which means the same thing, with the difference on a sexual level.
Quasi means "seemingly", or "apparently but not really". This means that other attractions can replace the romantic attraction, functioning as a romantic attraction.
