It is a very tough challenge that tell that who is the actual lover of gojo?
so,it have no specific answer.But we saw,in the hidden inventory,Gojo was hugely sad to know riko is died.And when he was fighting with Toji,he was talking about Toji
SO GOJO LOVEd RIKO(I think riko loved gojo)
In the shibuya incident,we saw mei mei was very exciting with gojo.But we didn't see that gojo is loving with mei mei
BUT,MEI MEI LOVES GOJO
